Question

11. John puts a fence around his rectangular backyard. The width of his backyard is 10 feet. He

uses 60 feet of fencing material in total. What is the length of his backyard?

Answer 1

Length = 20 ft

If he uses 60 ft of fencing to line his rectangular backyard, then the perimeter is 60 ft.

Perimeter formula is ((Width × 2) + (Length × 2))

10 × 2 = 20

20 × 2 = 40

40 + 20 = 60
