Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
In physics and mathematics area and volume is used to find the space covered or inside an object. This can be useful to determine things like the density or pressure of an object. Here you will learn the formulas of area and volume, how they are derived, why they make sense, and how to use these formulas relating to physics.
Area is the amount of space taken up by a 2D shape. 2D shapes are completely flat. To work out the area of a square or a rectangle, multiply its height by its width.
May 26, 2023 · Area is the term used to define the amount of space taken up by a 2D shape or surface. We measure area in square units : cm² or m². Area is calculated by multiplying the length of a shape by its width.

The area of a rectangleis the space occupied by it. Consider the yellow rectangle in the grid. It has occupied 6 units. In the above example, the length of the rectangle is 3 units and the width is 2 units. The area of a rectangle is obtained by multiplying its length and width which is the same as counting the unit squares. Thus, the formula for t...
The area of a squareis the space occupied it. Look at the colored square shown in the grid below. It occupies 25 squares. From the figure, we can observe that the length of each side of the colored square is 5 units. Therefore, the area of the square is the product of its sides which can be represented by the formula: Area of a square = side × side...
A circle is a curved shape. The area of a circle is the amount of space enclosed within the boundary of a circle. Learn more about π and radiusbefore we go to the formula for the area of a circle. The area of a circle is calculated with the help of the formula: π r2, where π is a mathematical constant whose value is approximated to 3.14 or 22/7 and...
