The answer is 120ft by 120ft. I just dont know how to get to the answer. I was thinking (x+40)(x+60)=14400. because parking lot area + area of the building = 14400. So I was trying to find the dimensions with the area given.

**Reiny**, Wednesday, September 2, 2009 at 10:45pmlet the side of the square be x ft

so I see x^2 - (60)(40) = 12000

x^2 = 14400

x = √14400 = 120
