## What is area formula?

Given a rectangle with length l and width w, the formula for the area is: **A = lw (rectangle)**. That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s^{2} (square).
