Question
Minimum cost. From a tract of land, a developer plans to fence a rectangular region and then divide it into two identical rectangular lots by putting a fence down the middle. Suppose that the fence for the outside boundary costs
per foot and the fence for the middle costs 
per foot. If each lot contains 
square feet, find the dimensions of each lot that yield the minimum cost for the fence.A) Dimensions are 48.07 ft for the side parallel to the divider and 85.29 ft for the other side.
B) Dimensions are 85.29 ft for the side parallel to the divider and 48.07 ft for the other side.
C) Dimensions are 64.03 ft for the side parallel to the divider and 64.03 ft for the other side.
D) Dimensions are 60.37 ft for the side parallel to the divider and 67.91 ft for the other side.
E) Dimensions are 67.91 ft for the side parallel to the divider and 60.37 ft for the other side.
