Question types: Area of rectangles and squares

Rule: Area of rectangles and squares

The area tells you how many unit squares fit inside the shape.

Rectangle: A = a × b, square: A = a × a. If you know the area and one side: b = A ÷ a.

Example: a = 8 m, b = 10 m: A = 8 × 10 = 80 m²

Watch out: Area has square units (cm², m²), perimeter doesn’t (cm, m).

Sample questions

  1. Question 1 Easy

    A rectangle has an area of 80 cm² and side a = 8 cm. How long is side b?

    Show the solution
    Answer: 10 cm

    How it works: b = A ÷ a = 80 ÷ 8 = 10 cm

  2. Question 2 Normal

    Work out the area of a square with side a = 4 m.

    Show the solution
    Answer: 16 m²

    How it works: A = a × a = 4 × 4 = 16 m²

  3. Question 3 Hard

    Work out the area of a rectangle with sides a = 7 m and b = 4 m.

    Show the solution
    Answer: 28 m²

    How it works: A = a × b = 7 × 4 = 28 m²
