  1. Joe is fencing in a square area of 576 square feet.
    Fence posts, which are needed every three feet, cost 32.00 each.
    The fencing cost 4.50 per foot. What is the total cost of the fencing materials?

    Solution:-
    Area of Square is 576 sq ft.
    so, the length of side = root(576) = 24 ft

    Since the fencing would be done on the perimeter, we would need that
    formula is 4*side = 96 ft.

    Number of Fence post needed = 96/3 = 32

    1 Fence post cost = 32
    32 Fence Post cost = 32 * 32 = 1024

    Fencing cost = Perimeter * fencing cost = 96 * 4.5 = 432

    Total Cost = 432 + 1024 = 1456
