What is Perimeter?

  • Perimeter is the distance around the outside of a shape.
  • It can be measured in cm, inches, feet, yards, km, miles, etc.

A good way of thinking about the perimeter of a shape in front of you is to imagine that you are very small and standing on one of the corners of the shape. Imagine walking along the sides of the shape until you get back to where you started. The distance you have walked will be the perimeter.

  1. Add up the lengths of each side separately: 7 + 2 + 7 + 2 = 18
  2. Double the lengths of the adjacent sides and add them: double 7 + double 2 = 14 + 4 = 18
  3. Add the adjacent sides and double the answer: double (7 + 2) = double 9 = 18
