Perimeter is another geometric concept that your child will begin learning in third grade. Perimeter is defined as the distance around a two-dimensional shape. Calculating perimeter requires addition and multiplication skills, so after your student has mastered those concepts, you can help them move on to our worksheet resources for perimeter.

Perimeter is the total length around a shape, and for different shapes, there are different ways to calculate it.

After you practice your perimeter skills with the resources on this page, you can then move over to our area resources to learn how to calculate the amount of space inside a shape.

- Square: perimeter = 4 × s, where s is the length of a side
- Rectangle: perimeter = 2 × (w + h), where w is width and h is height
- Triangle: perimeter = a + b + c, where a, b, and c are the lengths of three different sides
- Circle: the perimeter for a circle is actually called the circumference. Circumference = 2 × π × r, where r is the radius.
- Quadrilateral: perimeter = a + b + c + d, where a, b, c, and d are lengths of different sides

After you practice your perimeter skills with the resources on this page, you can then move over to our area resources to learn how to calculate the amount of space inside a shape.
