On this webpage you will find our range of worksheets to help your child learn to work out the perimeter of a range of rectangles.

Using these sheets will help your child to:

- find the perimeter of rectilinear shapes;
- know how to work out the side length of a rectangle if we know the 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.

To find the perimeter of a rectangle, there are several different ways, you can use the one you prefer:

- Add up the lengths of each side seperately
- Double the lengths of the adjacent sides and add them together.
- Add the adjacent sides and double the answer.

Find the perimeter of the rectangle below.

We will work the perimeter out using the 3 different ways above:

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

A rectilinear shape is a shape made up of two or more rectangles.
