Question

Can someone explain how to do this cuz my computer ain’t doing such a good job

Answer 1

length = 36 in and width = 6 in

Explanation:

let width be w then length (l) = 6w

perimeter = 2l + 2w = 2(6w) + 2w, that is

perimeter = 12w + 2w = 84, so

14w = 84 ( divide both sides by 14 )

w = 6

Thus

width = 6 in

length = 6w = 6 × 6 = 36 in

Answer 2

L=36

W=6

Explanation:

If the length is six times the width than the width is equal to x. This would make the length 6x or 6 times x. The perimeter of the rectangle is all of the sides added together. So 6x+6x+x+x=14x

The perimeter equals 84 which gives you

14x=84

Divide by 14 on each side and x=6

The length is six times longer than the width which is 6x6 or 36 and the width would just remain 6.
