Area - is the amount of space inside a two-dimensional shape. It is measured in square units (such as cm2). Perimeter - is the length of the outer edge of a two-dimensional shape. It is measured in linear units (such as cm). Lateral Area - is the area of the sides of a three-dimensional shape. It is measured in square units (such as cm2).

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.
