Combined area of 1680ft^2 for 4 identical rectangular corrals.

Corrals are joined together and no fencing at the back wall of the barn.

200=5d+4w

1680=4dw

What length will produce the maximum area?

d=12

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?

A=dw

A=(4)(12)(35)=1680ft^2
