  • 1. Calculating the Perimeter & Area of a Rectangle For more maths help & free games related to this, visit: www.makemymathsbetter.com
  • 2. The perimeter is the distance around the outside of a shape.
  • 3. 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:
  • 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 Width 4cm Length 15cm
  • 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 Width 4cm Length 15cm Perimeter = 15cm + 4cm + 15cm + 4cm = 38cm
  • 6. Length 15cm Width 4cm Width 4cm Length 15cm 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 Width 4cm Length 15cm 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 1cm 1cm 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 1cm 1cm 1cm Length 15cm Width 4cm Width 4cm Length 15cm
  • 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): 1cm 1cm 1cm 1cm Length 15cm Width 4cm Width 4cm Length 15cm You can work out the area by adding up the number of square cm. In this example there are 60cm²
  • 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): 1cm 1cm 1cm 1cm Length 15cm Width 4cm Width 4cm Length 15cm You can work out the area by adding up the number of square cm. In this example there are 60cm² Or you can multiply the length by width: 15 x 4 = 60cm²
