The area of a rectangle is the product of its length and width. If a rectangle’s sides are doubled, its area is quadrupled. The area of a circle is known as the circle’s “zone of influence”, or the space inside the circle’s perimeter. The circumference of a circle is the same as its perimeter, but the area is always different.
