A farmer wants to build a rectangular pen and then divide it with two interior fences. The total area inside of the pen will be 264 square meters. The exterior fencing costs $15.60 per meter and the interior fencing costs $13.00 per meter. Find the dimensions of the pen that will minimize the cost.

x = 12 m and y = 22 m

Step-by-step explanation:

Total area = 264

∴ xy = 264

      ............(1)

Cost function =

Therefore, using (1),

So, cost C(x) minimum where C'(x) = 0

m

Therefore,

                      = 22 m

So the dimensions are  x = 12 m and y = 22 m.
