The perimeter of a shape is the total distance around it, while area describes the amount of surface the shape uses or covers. Perimeter and area calculation methods differ for every kind of shape. For instance, while you can find the area of a rectangle simply by multiplying its length by its width, a circle requires a more complex calculation. This defines sectors whose areas can be calculated by using a geometric formula. The area of each sector is then used to approximate the area between successive Regardless of this fact, the curves intersect at the origin. This case must always be taken into consideration.
