When the length of a rectangle is increased by 20% and the width increased by 10%, by what percent is the area increased?

Say L (the length) is 10, and W (the width) is also 10.

The area of this rectangle would be 10 * 10 = 100 square units.

With the newer figures, we get the sides to be L = 12 and W = 11. The area of this is 12 * 11 = 132.

132 is a **32% increase** from 100 :D

L x W = A

1.2 L x 1.1 W = 1.32 L X W 1.32 corresponds to increase 1.32 times original A....or 32% increase
