What is the perimeter of a square with side length of 5cm

The perimeter is 20 cm. ( remember to put the unit...)

Step-by-step explanation:

The formula for finding the perimeter of a square is 4s or s + s + s + s

In this case, the side length is 5 cm.

So plug in the values

4s                                  s + s + s + s

4 ( 5 )                             5 + 5 + 5 + 5

20                                      20
