A farmer wants to fence an area of 13.5 million square feet in a rectangular field and then divide it in half with a fence parallel to one of the sides of the rectangle. Let y represent the length (in feet) of a side perpendicular to the dividing fence, and let x represent the length (in feet) of a side parallel to the dividing fence. Find the critical numbers of the function and what the lengths of the sides of the rectangular be(in ft) in order to minimize the cost of the fence.
