Typing paper measures 8 1/2 inches wide and 11 inches long. find the perimeter of the typing paper.

The perimeter it how long it is all the way around, so all of the sides added together.

We know it measures 8 1/2 inches wide, and 11 inches long.

So now we know all of the sides would be 8 1/2+8 1/2+11+11.

8 1/2+8 1/2=17, and 11+11=22, 17+22=39

The perimeter of the typing paper is 39 inches.

Perimeter = the length of all the sides added up

8 1/2 + 8 1/2 = 17

11 + 11 = 22

22 + 17 = 39

Answer = 39in
