Perimeter

# Perimeter: Find the perimeter

The perimeter of a shape is the distance around the outside of the shape. Find the perimeter by adding the lengths of the sides.

What is the perimeter of this parallelogram?

In a parallelogram, opposite sides have the same length.

Look at the parallelogram and find the side lengths. add:

3+6+3+6=18

Now find the units. The lengths are measured in feet, so the perimeter is also measured in feet.

The perimeter is 18 feet.

What is the perimeter of this square?

 14 mm

The perimeter is mm
