The area of a trapezoid with
bases b%5B1%5D and b%5B2%5D ,
and height h is
area=%28b%5B1%5D%2Bb%5B2%5D%29%2Ah%2F2 .
In this case, the area in square feet is
%28100%2B80%29%2A60%2F2=180%2A60%2F2=5400 .
The cost to cover with grass 5400 square feet at $0.35 per square foot is
5400%2A%28%22%24+0.35%22%29=%22%241990%22 .
