A farmer needs to build a rectangular enclosure with two unequal compartments, one containing 180 ft of area and the other 300 ft, as shown in the diagram to the right. a) What values of L and W that would minimize the amount of fence that the farmer must use? b) The length of fence that serves as a divider between the two compartments must be made from a special material, so that the cost per length is twice that of the outer fence. What values of L and W would minimize the total cost of fencing for the enclosure? Given: Find: 180 ft 300 ft W L
