Question 1155281: A cattle rancher would like to fence an area of 180 square miles by first fencing the whole area and then running a fence across the middle from front to back. The rancher wants the exterior fence to be stronger than the interior fence and so will use fencing that costs $6 per mile along the outer perimeter and fencing that costs $3 per mile down the middle. What dimensions should the area have so that the total cost of fencing is minimized? What is this minimum cost?
