Area and Perimeter
This lesson is on finding the area and perimeter of a figure. It is important that students understand that area means the amount of space that the figure covers. Perimeter is the length it takes to go around the entire figure. I have provided a link to some practice problems. There are also a few word problems involving area and perimeter at the bottom of this page.

Sample Word Problems:
1. Zoe is putting a border around her blanket and needs to know how much ribbon to buy. The length of the blanket is 3 times the width of the blanket. If the length of the blanket is 6 yards, what is the width of the blanket? What is the perimeter of the blanket (so she know how much ribbon she needs to go around it)?
2. An amusement park has a length of 25 miles. If the length is 5 times the width, what is the width of the park? What is the area of the park?
3. The length of New Jersey is 9 times the width of New Jersey. If the length is 441 kilometers, what is the area of New Jersey?
4. The school is building a fence around its playground and they need to know how much fencing to buy. The length of the playground area is 5 times its width. If the length is 300 feet, what is the width? What is the perimeter and how much fencing do they need to go around it?
5. The length of Sam's pool is 24 feet. The area of the pool's surface is 144 square feet. What is the perimeter of the pool?
