Perimeter of Different Shapes Worksheets - Regular Shapes

Finding the Perimeter of a Regular Shape

Because regular shapes have all sides of equal length, we can easily find the perimeter of a regular shape.

All we need to do is to multiply the number of sides by the length of one side to find the perimeter.

Finding the side length of a Regular Shape

If we know the perimeter of a regular shape, we can also easily find the side length.

All we need to do is to divide the perimeter by the number of sides to find the length of one side.

Perimeter of Different Shapes Worksheets - Assorted 2d Shapes

These sheets involve finding the perimeter of assorted shapes.

Each sheet consists of a range of 2d shapes to find the perimeter of.

Some of the sheets need measurement to find the perimeter, others involve adding up the side lengths.

Each sheet has two versions: a standard unit version (with both standard and metric units) and also a metric version with metric units only.
