**Steve**, Wednesday, February 29, 2012 at 12:17pmIf the width is w, then the length is 42-2w. So, the area is

y = w(42-2w)

y = -2w^2 + 42w

this is just a parabola, and y reaches its maximum when w = -42/-4 = 10.5

so, the pasture is 10.5 x 21. Area = 220.5

If we want just 220 m^2, then the field is 11x20
