A farmer uses 36 feet of fencing to build a rectangular rabbit pen. The function A(w)=18w−w2 can be used to find the area of the
pen for a given width, w.
The farmer finds that the average rate of change over the interval w=3 to w=9 is 6.
What does this mean in terms of the dimensions of the rabbit pen?
