Exercise 7 Page 642

Use the formula for the area of a parallelogram A=bh.

12in.

Practice makes perfect

We are told that the area of a parallelogram is 36 in.^2, and its height is 3 inches. We are asked to find the length of the corresponding base.

We are going to substitute values A= 36 in.^2 and h= 3 in. into the formula for the area of a parallelogram. Next, we will solve for b.

A=bh

A= 36, h= 3

36=b(3)

Multiply

36=3b

.LHS /3.=.RHS /3.

12=b

Rearrange equation

b=12

The base of the parallelogram is 12 inches.
