The perimeter of a rectangle is 72 inches the width is twice the length find the width

Answer 1

Width is 24 inches

Given

Perimeter = 72

Width = 2*Length

Let P = Perimeter

Let W = Width

Let L = Length

Knowing

P = 2L + 2W = 72

W = 2L

We can rewrite everything in terms of Length

72 = 2L + 2(2L)

72 = 2L + 4L

72 = 6L

72/6 = L

12 = L

W = 2L

W = 2(12) = 24

Width is 24

Length is 12

Checking

72 = 2(12) + 2(24)

72 - 24 + 48

I hope this helps
