    The largest area would be closest to a square. Divide 1932 by 4.

    I tried that answer and it didn't work, the question wants the dimensions of the corral: length and width.

    Try PsyDAG's answer.

    Tried 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.

    well, 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.
