Hi, I don't understand what this question is asking and I have idea how to do it.. any help is very much appreciated! I understand how to complete the square, parabolas and such and the concept of maximum and minimum, I just don't understand this question. A Cattle farmer wants to build a rectangular fenced enclosure divided into 5 rectangular pens. Each pen has equal area. [diagram shows picture of 5 rectangular pens side by side, all of them are the same size] A total length of 120 m of fencing material is available. Find the overall dimensions of the enclosure that will make the total area a maximum.
