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

15 3/5 - (-5 2/10) =
15 3/5 + 5 2/10 =
15 + 5 = 20
3/5 + 2/10 = 6/10 + 2/10 = 8/10 reduces to 4/5
20 + 4/5 = 20 4/5
so ur answer is 20 4/5
