Trevor wants to build a rectangular pen for his animals. One side of the pen will be against the barn;
the other three sides will be enclosed with wire fencing. If Trevor has 750 feet of fencing, what
dimensions would maximize the area of the pen?
(a) Let w be the length of the pen perpendicular to the barn. Write an equation to model the area
of the pen in terms of w
Area =
(b) What width w would maximize the area?
W=
