Combined area of 1680ft^2 for 4 identical rectangular corrals.
Corrals are joined together and no fencing at the back wall of the barn.
What length will produce the maximum area?
The dimensions of each corral (lxw) is 12'x35'
What will be the resulting maximum combined area of 4 corrals? The combined area would also mean maximum area, correct?
for maximum area, consider
a = 4dw = 4w(200-4w)/5
maximum a at w = 25 (midway between the roots of 0,50)
4dw = 75*25 = 1875 is the maximum area
