In the back of Lara and Brenda's apartment is a patio. The dimensions of the rectangular patio are 25 by 20 feet. A concrete sidewalk runs diagonally from their 3-foot-wide back door to the gate through the fence. They want to buy sod or grass to cover the part of the patio outside the concrete walkway. How many square feet of sod do they need?
