5. A fence must be built to enclose a rectangular area of 2,000 ft². Fencing material costs $2.50 per foot for the two sides facing north and south, and $2.00 per foot for the other two sides. Find the cost function and use derivative to find the dimension of the least expensive fence. What is the minimum cost?
