What is the perimeter of a rectangle that has a length of 9 cm and width of 6 cm ?

To start you off we know that a rectangle has 4 sides. So if the length of one side is 9 cm, it's going to be 9 cm also for the other side. So know we know, we have two six's and two nine's. So you're going to add all those together and your and answer would end up being 30 cm.
