Area of Rectangles: KS2 Maths Help
23 October 2026
Rectangles are a key shape in primary maths, and learning to find their area helps children build confidence with measuring space. The formula for area is simple and always the same for rectangles.
Example question
Find the area of a rectangle with length 5 cm and width 3 cm.
Step 1: Write down the formula for the area of a rectangle.
Area = length × width
Step 2: Put the numbers into the formula. Area = 5 cm × 3 cm
Step 3: Multiply the numbers. Area = 15 cm²
Answer: The area of the rectangle is 15 square centimetres.
After working through this example, your child will recognise how to use the formula for any rectangle. The next step is to practise with similar questions to build up speed and accuracy.
