Answer:

Length = 120 ft

Total cost = 1500$

Step-by-step explanation:

First, to find the length of the backyard we reverse the formula (A = l * w) and divide 10,800 by 90.

10,800 ft^2 / 90 ft = 120 ft.

we can check this by plugging the length of 120 ft into the formula:

120 ft * 90 ft = 10,800 ft^2.

Next, to find the cost of the single length of fence we multiply our length (120 ft) by the cost ($12.50):

120 * 12.50 = $1500
