Exercise 20 Page 289

To find the area of a parallelogram, calculate the product of the base and the height.

243 square inches

Practice makes perfect

The area of a parallelogram is the product of its base and its height. In the given parallelogram, the length of the base is 13.5 inches and the height is 18 inches.

We can substitute these two values into the formula for the area of a parallelogram and simplify.

A=bh

b= 13.5, h= 18

A= 13.5( 18)

Multiply

A=243

The area of the parallelogram is 243 square inches.
