A parking space shaped like a parallelogram has a base of 19 feet and a height is 8 feet. A car parked in the space is 13 feet long and 4 feet wide. How much of the parking space is not covered by the car?

First, we have to get the area of the parallelogram. A = b x h. 

A = 17 feet x 9 feet

A = 153 square feet.

The area of the car (assume that the car is rectangle) is equal to: A = l x w.

A = 16 x 6

A = 96 square feet.

The space that is not covered by the car is 153 - 96 = 37 square feet.
