Suppose a farmer wants to fence off a rectangular field alongside a river with a total area of 15, 000 m². The three sides that do not border the river will cost $10 per meter while the side that borders the river will cost $20 per meter since it must be taller. What should the dimensions of the field be so as to minimize the total cost?
