2. The perimeter is the distance around the outside of a shape.

3. To work out the perimeter of a rectangle, you add up the lengths and the widths. For example:

4. The perimeter is the distance around the outside of a shape. To work out the perimeter of a rectangle, you add up the lengths and the widths. For example: Length 15cm Width 4cm

5. The perimeter is the distance around the outside of a shape. To work out the perimeter of a rectangle, you add up the lengths and the widths. For example: Length 15cm Width 4cm Perimeter = 15cm + 4cm + 15cm + 4cm = 38cm

6. Length 15cm Width 4cm A quicker way to find the perimeter of a rectangle is to add up one of the lengths with one of the widths and then double that answer

7. Length 15cm Width 4cm A quicker way to find the perimeter of a rectangle is to add up one of the lengths with one of the widths and then double that answer For example, (15cm + 4cm) x 2 = 38cm

8. Area is the amount of space that is covered by a 2D shape. It is measured in square units. For example a square cm (written cm²): 1cm

9. Area is the amount of space that is covered by a 2D shape. It is measured in square units. For example a square cm (written cm²): 1cm Length 15cm Width 4cm

10. Area is the amount of space that is covered by a 2D shape. It is measured in square units. For example a square cm (written cm²): You can work out the area by adding up the number of square cm. In this example there are 60cm² 1cm Length 15cm Width 4cm

11. Area is the amount of space that is covered by a 2D shape. It is measured in square units. For example a square cm (written cm²): You can work out the area by adding up the number of square cm. In this example there are 60cm² 1cm Length 15cm Width 4cm Or you can multiply the length by width: 15 x 4 = 60cm²
