A college is planning to construct a rectangular parking lot on land bordered on one side by a highway. the plan is to use 400 feet of fencing to fence off the other three sides. what dimensions should the lot have if the enclosed area is to be a​ maximum

Respuesta :

400 ÷ 3 = 133 1/3

So the perimeter of the 3 sides will be 133 + 133 + 134, making it 400
Total area = 133 x 134 = 17822 square feet

So the dimension is 133 by 134 feet
