Geometry Practice: Perimeter Worksheets

Finding the perimeter of a two-dimensional figure is an important geometry skill for young students in grades two and above. Perimeter refers to the path or distance that surrounds a two-dimensional shape. For instance, if you have a rectangle that is four units by two units, you can use the following calculation to find the perimeter: 4+4+2+2. Add each side to determine the perimeter, which is 12 in this example.

The five perimeter worksheets below are in PDF format, allowing you to print them individually or for a classroom of students. To ease grading, the answers are provided the second page of each PDF.

Perimeter Worksheet No. 1

Find the Perimeter

D. Russell

Print the PDF: ​Worksheet No. 1

Students can learn how to calculate the perimeter of a polygon in centimeters with this worksheet. For example, the first problem asks pupils to calculate the perimeter of a rectangle with sides of 13 centimeters and 18 centimeters. Explain to students that a rectangle is essentially a stretched-out square with two sets of two equal sides. So, the sides of this rectangle would be 18 centimeters, 18 centimeters, 13 centimeters, and 13 centimeters. Simply add the sides to determine the perimeter: 18 + 13 + 18 + 13 = 62. The perimeter of the rectangle is 62 centimeters.

Perimeter Worksheet No. 2

Find the Perimeter

Print the PDF: Worksheet No. 2

In this worksheet, students must determine the perimeter of squares and rectangles measured in feet, inches, or centimeters. Use this opportunity to help students learn the concept by walking around—literally. Use your room or classroom as a physical prop. Start in one corner, and walk to the next corner as you count the number of feet you walk. Have a student record the answer on the board. Repeat this for all four sides of the room. Then, show students how you would add the four sides to determine the perimeter.

Perimeter Worksheet No. 3

Find the Perimeter

D. Russell

Print the PDF: Worksheet No. 3

This PDF includes several problems that list the sides of a polygon in inches. Prepare ahead of time by cutting out pieces of paper—one for each student—that measure 8 inches by 7 inches (No. 6 on the worksheet). Pass out one piece of precut paper to each student. Have the students measure each side of this rectangle and record their answers. If the class seems to understand the concept, allow each student to add up the sides to determine the perimeter (30 inches). If they are struggling, demonstrate how to find the perimeter of the rectangle on the board.

Perimeter Worksheet No. 4

Find the Perimeter

D. Russell

Print the PDF: Worksheet No. 4

This worksheet increases the difficulty by introducing two-dimensional figures that are not regular polygons. To help students, explain how to find the perimeter of problem No. 2. Explain that they would simply add the four sides that are listed: 14 inches + 16 inches + 7 inches + 6 inches, which equals 43 inches. They would then subtract 7 inches from the bottom side, 16 inches to determine the length of the top side, 10 inches. They would then subtract 7 inches from 14 inches, to determine the length of the right side, 7 inches. Students can then add the total they determined previously to the remaining two sides: 43 inches + 10 inches + 7 inches = 60 inches.

Perimeter Worksheet No. 5

Find the Perimeter

D. Russell

Print the PDF: Worksheet No. 5

This final worksheet in your perimeter lesson requires students to determine perimeters for seven irregular polygons and one rectangle. Use this worksheet as a final test for the lesson. If you find the students are still struggling with the concept, explain again how to find the perimeter of two-dimensional objects and have them repeat the previous worksheets as needed.
