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

**Steve**, Saturday, October 6, 2012 at 2:40pmfor 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
