**MathMate**, Monday, March 5, 2012 at 10:26amSince length x width = area

we have length=area/width

Let

w=width of the pasture, and

320000/w=length (parallel to river) of pasture

Total length of fencing

F=twice width + length

=2w + 320000/w

Find derivative of F with respect to w and equate to zero to find w.

i.e.

Solve for w in

dF/dw=0
