No, that would only be 1600 sq. ft. (40x40). Try a 30x60, that gives you a total of 1800 sq. ft. (The three sides are 30, 60, and 30, for a total of 120 feet of fence. The length and width are 30 and 60).

That would make it a square, not a rectangle. Did they give the length of the buliding? The area would remain constant given a fixed perimeter. 40x40 = 20x80
