More about the area

General information

Area is the size of a geometric figure in two-dimensional space. It is used in mathematics, medicine, engineering and other sciences, for example in calculating the cross-section of cells, atoms, or pipes such as blood vessels or water pipes. In geography, area is used to compare the sizes of cities, lakes, countries, and other geographic features. Population density calculations also use area. Population density is defined as the number of people per unit area.

Units

Square meters

Area is measured in SI units in square meters. One square meter is the area of a square with a side of one meter.

Unit square

A unit square is a square with sides of one unit. The area of a unit square is also equal to one. In a rectangular coordinate system, this square is located at coordinates (0,0), (0,1), (1,0) and (1,1). On the complex plane the coordinates are 0, 1, i And i+1, where i- imaginary number.

Ar

Ar or weaving, as a measure of area, is used in the CIS countries, Indonesia and some other European countries, to measure small urban objects such as parks when a hectare is too large. One are is equal to 100 square meters. In some countries this unit is called differently.

Hectare

Real estate, especially land, is measured in hectares. One hectare is equal to 10,000 square meters. It has been in use since the French Revolution, and is used in the European Union and some other regions. Just like the macaw, in some countries the hectare is called differently.

Acre

In North America and Burma, area is measured in acres. The hectares are not used there. One acre is equal to 4046.86 square meters. An acre was originally defined as the area that a farmer with a team of two oxen could plow in one day.

Barn

Barns are used in nuclear physics to measure the cross section of atoms. One barn is equal to 10⁻²⁸ square meters. The barn is not a unit in the SI system, but is accepted for use in this system. One barn is approximately equal to the cross-sectional area of a uranium nucleus, which physicists jokingly called “as huge as a barn.” Barn in English is “barn” (pronounced barn) and from a joke among physicists this word became the name of a unit of area. This unit originated during World War II, and was liked by scientists because its name could be used as a code in correspondence and telephone conversations within the Manhattan Project.

Area calculation

The area of the simplest geometric figures is found by comparing them with the square of a known area. This is convenient because the area of the square is easy to calculate. Some formulas for calculating the area of geometric figures given below were obtained in this way. Also, to calculate the area, especially of a polygon, the figure is divided into triangles, the area of each triangle is calculated using the formula, and then added. The area of more complex figures is calculated using mathematical analysis.

Formulas for calculating area

Square: square side.
Rectangle: product of the parties.
Triangle (side and height known): the product of the side and the height (the distance from that side to the edge), divided in half. Formula: A = ½ah, Where A- square, a- side, and h- height.
Triangle (two sides and the angle between them are known): the product of the sides and the sine of the angle between them, divided in half. Formula: A = ½ab sin(α), where A- square, a And b- sides, and α - the angle between them.
Equilateral triangle: side squared divided by 4 and multiplied by the square root of three.
Parallelogram: the product of a side and the height measured from that side to the opposite side.
Trapezoid: the sum of two parallel sides multiplied by the height and divided by two. The height is measured between these two sides.
Circle: the product of the square of the radius and π.
Ellipse: product of semi-axes and π.

Surface Area Calculation

You can find the surface area of simple volumetric figures, such as prisms, by unfolding this figure on a plane. It is impossible to obtain a development of the ball in this way. The surface area of a sphere is found using the formula by multiplying the square of the radius by 4π. From this formula it follows that the area of a circle is four times less than the surface area of a ball with the same radius.

Surface areas of some astronomical objects: Sun - 6,088 x 10¹² square kilometers; Earth - 5.1 x 10⁸; thus, the surface area of the Earth is approximately 12 times smaller than the surface area of the Sun. The Moon's surface area is approximately 3.793 x 10⁷ square kilometers, which is about 13 times smaller than the Earth's surface area.

Planimeter

The area can also be calculated using a special device - a planimeter. There are several types of this device, for example polar and linear. Also, planimeters can be analog and digital. In addition to other functions, digital planimeters can be scaled, making it easier to measure features on a map. The planimeter measures the distance traveled around the perimeter of the object being measured, as well as the direction. The distance traveled by the planimeter parallel to its axis is not measured. These devices are used in medicine, biology, technology, and agriculture.

Theorem on properties of areas

According to the isoperimetric theorem, of all figures with the same perimeter, the circle has the largest area. If, on the contrary, we compare figures with the same area, then the circle has the smallest perimeter. The perimeter is the sum of the lengths of the sides of a geometric figure, or the line that marks the boundaries of this figure.

Geographical features with the largest area

Country: Russia, 17,098,242 square kilometers, including land and water. The second and third largest countries by area are Canada and China.

City: New York is the city with the largest area of 8683 square kilometers. The second largest city by area is Tokyo, occupying 6993 square kilometers. The third is Chicago, with an area of 5,498 square kilometers.

City Square: The largest square, covering 1 square kilometer, is located in the capital of Indonesia, Jakarta. This is Medan Merdeka Square. The second largest area, at 0.57 square kilometers, is Praça doz Girascoes in the city of Palmas, Brazil. The third largest is Tiananmen Square in China, 0.44 square kilometers.

Lake: Geographers debate whether the Caspian Sea is a lake, but if so, it is the largest lake in the world with an area of 371,000 square kilometers. The second largest lake by area is Lake Superior in North America. It is one of the lakes of the Great Lakes system; its area is 82,414 square kilometers. The third largest lake in Africa is Lake Victoria. It covers an area of 69,485 square kilometers.

The length of everything is measured in inches or feet. Feet is a plural form of foot, which is not a unit of length in the Imperial and American measurement systems. However, when describing an architectural space - a rectangle or a square - the area must be calculated using two dimensions, since area is a two-dimensional dimension. The area of a room is calculated by multiplying the length and width of the room in feet. For example, if a room is 15 feet long and 12 feet wide, then the area of the room is 15 times 12, which is 180 square feet.

Difference between feet and square feet

Foot Fundamentals Vs. Square foot

Feet (plural feet) is a non-SI unit for measuring length, as specified in Imperial and American units. It is used to measure height, length and distance. The square foot is a non-SI unit for measuring area, primarily in the United States. It is the plural of square foot, used to measure any two-dimensional space.

Symbol and calculation of feet Vs. Square foot

The international symbol for feet is "feet", while square feet are symbolized as "sq ft." Or "ft 2". The area of a rectangular or square room is calculated in square feet by multiplying the length and width of the room in feet. If the room is 12 feet long and 12 feet wide, then the area of the room is (12 * 12) 144 sq.

Leg Transformation Vs. Square foot

1 foot converts to 12 inches or 0.3048 meters. Likewise, 1 square meter is equivalent to 0.092903 square meters or 144 square inches. Area of 1 sq. Feet would be 12*12 inches square. Feet is a one-dimensional unit, and square feet is a two-dimensional unit for an area.

Examples of feet Vs. Square foot

If a room measures 15 feet long and 10 feet wide, then the area of the room is calculated as:

Area = 15 x 10 = 150 square feet or 150 sq. ft or 150 ft 2

Feet vs. Square Feet: Comparison Chart

Summary of feet and square feet

When you measure the length of anything, it is measured in inches or feet, but area is a two-dimensional dimension, so it is calculated in two dimensions - length and width. To calculate architectural space in square feet, length and width are measured in feet and then multiplied together to give area in square feet or ft2. Foot is a non-SI unit for measuring length, whereas square foot is unit of measure unit of measurement other than SI.
