**Diane**, Friday, October 4, 2013 at 1:04pmTried that too and still didn't work. the picture has a rectangular fence with a fence going across the middle from longest side to the opposite side.

**Steve**, Friday, October 4, 2013 at 3:27pmwell, if you want a correct answer, you need to pose the correct question. If the short side is x and the long side is y, then

2y+3x = 1932, so y = (1932-3x)/2

area = xy = x(1932-3x)/2 = (1932x-3x^2)/2

This is a parabola, with vertex at x=322.

You can probably take it from there. Note that just as PsyDiag suggested, the fencing is evenly divided between length and width.
