Question

Using the figures below, what is the perimeter of the 5th rectangle in the pattern?

Answer 1

First: 1, 2

Second: 2, 3

Third: 3, 4

Fourth: 4, 5

Fifth: 5, 6

Perimeter = 5 + 5 + 6 + 6 = 22

Answer: 22

Answer 2

Each side is increasing their length by 1 every time, and the length is always 1 greater than the height. That means the 5th rectangle will have a height of 5 and a length of 6, which would give it a perimiter of 22.
