Question

Mr. Sanchez built a fence to enclose a rectangular
yard for his horse. If the area of the yard to be
enclosed is 2835 square feet, and the length of
the yard is 45 feet, how much fencing is needed?

Answer 1

9514 1404 393

Answer:

  216 feet

Step-by-step explanation:

The area is given by the formula ...

  A = LW

Solving for width, we have ...

  W = A/L = 2835 ft²/(45 ft) = 63 ft

__

The perimeter is given by the formula ...

  P = 2(L +W)

  P = 2(45 ft +63 ft) = 2(108 ft)

  P = 216 ft

216 feet of fencing are needed to enclose the area.
