Question

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)

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

Answer 1

Answer: 60 in.

Chain of Thought Reasoning:

Step 1: P = 2L + 2W

Step 2: 18 = 2L + 2(4)

Step 3: 18 = 8 + 2L

Step 4: 10 = 2L

Step 5: 5 = L

Step 6: Convert feet to inches: 1 foot = 12 inches

Step 7: 5 feet = 5 * 12 inches

Step 8: 5 feet = 60 inches

Therefore, the length of the rectangular yard is 60 inches.
