Sarah fenced in her backyard. The perimeter of the yard is 18 feet, and the width of the yard is 4 feet. Use the perimeter formula to find the length of the rectangular yard in inches: P = 2L + 2W. (1 foot = 12 inches)

Question

96 in.
60 in.
10 in.
5 in.

Answer 1

Let L represent the length of the yard in feet.

Given:
Perimeter (P) = 18 feet
Width (W) = 4 feet

Perimeter formula:
P = 2L + 2W
Substitute the given values:
18 = 2L + 2(4)
18 = 2L + 8

Subtract 8 from both sides:
10 = 2L
Divide by 2:
L = 5 feet
Convert feet to inches:
5 feet x 12 inches/foot = 60 inches

Therefore, the length of the rectangular yard is 60 inches. The correct answer is:
60 in.
