4. A farmer wants to build a fence in the configuration shown, with a total area of 3000 square feet. The internal fencing costs $4 per foot, and then fencing around the outside costs $10 per foot. What are the dimensions of the field that will minimize the cost of fencing? What is the lowest possible cost to build such a fence? Use the Second Derivative Test to confirm that your answer yields the minimum cost. y ft xft Lowest cost
