Suppose that you have 760 feet of rope and want to use it to make a rectangle. What dimensions should you make your rectangle if you want to enclose the maximum possible area?

Question

I thought I solved this question, but apparently I'm wrong. I found the maximum area enclosed to be 36075 square feet. My dimensions were 185 ft by 195 ft. The maximum area was right, but my dimensions are wrong. it's driving me crazy. What else could the dimensions possibly be if the amount of rope is 760 feet and the maximum area is 36075 ft^2????

Answer 1

760/4= 140 by 140 feet gives max area = 140^2 = 19,600 ft^2
