The Carsons are putting a rectangle swimming pool in their yard. It will measure 20ft by 12ft. They plan to have a cement walkway around the pool which should measure 4 ft wide. What is the area of the walkway?

area of pool = 20 by 12 or 240 square feet
area of pool + walkway = 28 by 20 = 560 square feet
area of walkway = 560240 = 320 square feet
