Problema Solution
A farmer wants to enclose a rectangular field along a river on three sides. If 3,200 feet of fencing is to be used, what dimensions will maximize the enclosed area?
Answer provided by our tutors
The width is x and length is (1600-x)
Area = x(1600-x)= -x^2+1600x
When x=800, area is max
So the dimension of 800x800 will maximize the enclosed area
