Area Definition

An area is defined as the amount of space covered by a flat two-dimensional surface (like circle or triangle) and a three-dimensional surface (like a sphere). In mathematics, it is used to measure the space covered by an object or entity.

However, the formula of finding the area of every object is different. For instance, to find the area of a rectangle, the length is multiplied by the rectangle’s width (A = lb).

Let us have another example of finding the area of a three-dimensional object like a cylinder. The formula used to find the cylinder will be different from the rectangle because of the difference in shape. The area of cylinder = 2πr (h + r). So remember, the area depends upon the shape of an object.
