Area of Rectangles

Calculate the area of these rectangles:

  • Length: 2cm, width: 3cm
  • Length: 4.5cm, width: 2cm
  • Length: 6cm, width: 3.5cm
  • Length: 4cm, width: 3cm
  • Length: 5cm, width: 5.5cm
  • Length: 2.5cm, width: 4cm


  • Explain the difference between perimeter and area. 


  • 2cm x 3cm = 12cm2
  • 4.5cm x 2cm = 9cm2
  • 6cm x 3.5cm = 21cm2
  • 4cm x 3cm = 12cm2
  • 5cm x 5.5cm = 27.5cm2
  • 2.5cm x 4cm = 10cm2

Challenge Answer

Perimeter measures the distance around a 2-D shape. Area is the size of the surface of a 2-D shape.
