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

Answer 1

• So first step would be convert 18 feet to inches, so 18 x 12 = 216

• Next step would be convert 4 feet to inches, so 4 x 12 = 48

• You then substitute these values into the perimeter formula, so 216 = 2L + (48 x 2)

• You then simply that to 216 = 2L + 96
• Then subtract 96 from both sides to get 120 = 2L
• And then divide both sides by two, and you'll get 60 = L

And so your answer should be 60 inches, hope this helps c:
