**Steve**, Sunday, October 20, 2013 at 5:42amsplit the fence equally between length and width. So, two pens of 2000x3000. I make that 12,000,000.

To be sure, use algebra.

If the pens are x long ad y wide, then

2x+3y = 12000

area = 2xy = 2x(12000-2x)/3

This is a parabola with vertex at (3000,12000000)
