Question

PLEASE HELP

Answer 1

width = 10 feet → C

let l represent the length then width = l - 8

perimeter = 2(length + width) = 2(l + l - 8)

given perimeter = 56 then

2(2l - 8)= 56

divide both sides by 2

2l - 8 = $\frac{56}{2}$ = 28

add 8 to both sides

2l = 28 + 8 = 36

divide both sides by 2

l = $\frac{36}{2}$ = 18

thus length = 18 feet and width = 18 - 8 = 10 feet
