**drwls**, Sunday, October 26, 2008 at 3:25pmThe area that he encloses for the pen is x * L, where L is the length of the existing fence that he uses. The fence material that he has can cover a length

2 x + L = 500

The area enclosed is therefore

A = x L = x*(500 - 2x) = 500 x -1000 x^2

Are you supposed to choose x to maximize area? If so, set dA/dx = 0 and solve for x.
