Area & Perimeter
Measure inside and around shapes
What your child practises
Finding the area and perimeter of squares and rectangles, working backwards to a missing side, and discovering that shapes with the same area can have different perimeters (and vice versa).

Sample questions
A taste of this unit. In the app, questions change every time and get easier or harder to match your child.
Question 1
A rectangular garden is 13 m long and 11 m wide. What is its area?
🌻13 m × 11 manswer boxm²
143 m²
Hint: Area of a rectangle = length × width. The answer is in square units.
Question 2
How many square units cover this rectangle?
🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩🟩answer boxsquare units
42 square units
Hint: Count the squares in one row, then multiply by the number of rows: area = rows × columns.
Question 3
Rectangles A and B have the same perimeter. Which statement is true?
Rectangle Length Width A 14 cm 6 cm B 16 cm 4 cm - Rectangle A has the greater area.
- Rectangle B has the greater area.
- They have the same area.
Rectangle A has the greater area.
Hint: Find each area: length × width. Same perimeter does not mean same area!
Question 4
What does perimeter measure?
- The space inside a shape
- How heavy a shape is
- How many corners a shape has
- The distance around a shape
The distance around a shape
Hint: Think of walking along the edge of a shape: that distance is the perimeter.
Question 5
A rectangular park is 20 m long and 12 m wide. How far is it to walk once around the edge?
answer boxm
64 m
Hint: Perimeter is the distance around: add all four sides, or work out 2 × (length + width).
Question 6
These rectangles all have a perimeter of 22 m. Which one has the greatest area?
- 8 m by 3 m
- 9 m by 2 m
- 6 m by 5 m
- 7 m by 4 m
6 m by 5 m
Hint: Work out length × width for each one. For the same perimeter, the closer the shape is to a square, the greater the area.
