Unknown Side Perimeter Word Problems
How is perimeter used in our everyday lives? When we install fencing, hang wallpaper, or put up Christmas lights, perimeter is a math concept that is used all the time! If your students have learned the basics of perimeter, then this worksheet will make a great supplement to use in your math class.

The perimeter of the coffee shop is 200 feet. The length is 60 feet. What is the width of the coffee shop?
Mr. Long is raking leaves. He is using a tarp with a perimeter of 48 meters. It is 14 meters long. What is the width?
