The distance between two adjacent vertices of a square gives the length of a side, s. The perimeter is then given by 4s.

To find the distance between two points (,) and (,), use the distance formula:

The perimeter is then , however, you were instructed to express your answer to the nearest tenth, therefore you should write 40.0 as your answer.

Hope this helps,
