A rectangular lot is to be fenced in using two different kinds of fencing. Three sides will be fenced with a standard fencing that costs $7/m, and the final side is next to a parking lot so it requires heavier, more expensive fencing at $9/m. If the company has $14 000 to spend on materials, what should the dimensions of the lot be to maximize the area enclosed by the fence?
