Is your 6 yards of fencing a misprint? That is not enough to enclose the required area.

Then L*W = 352 and
2(L + W) = 60
Solve the two simultaneous equations. Let L = 352/W
2(352/W +W) = 60
(352/W) + W = 30
W^2 - 30W + 352 = 0
There is no real solution. 60 yards of fencing is not enough to enclose 352 sq. yards. You need at least 75 yards
