The perimeters of these rectangles are the same. Write an equation and solve for x.

Perimeter of left rectangle

Perimeter of right rectangle

P = x + x + 5 + x + x + 5

P = x – 4 + 2x + x – 4 + 2x

= 4x + 10

= 6x – 8

Since the perimeters are the same, set them equal to each other

10 = 2x – 8

4x + 10 = 6x – 8
