Question

A rectangular photo has a perimeter of 60 inches. If the length is twice the width,

find the length and width of the photo.

Answer 1

length = 20 inches

width = 10 inches

Explanation:

Perimeter = twice the length plus twice the width

60 = 2(2x) + 2(x)

60 = 4x + 2x

60 = 6x

x = 10

2x = 20

Answer 2

length = 20 inches

width = 10 inches

Explanation:

Perimeter = twice the length plus twice the width

60 = 2(2x) + 2(x)

60 = 4x + 2x

60 = 6x

x = 10

2x = 20
