Show answers and working
1. Perimeter 56 cm, area 196 cm²
Perimeter = 14 + 14 + 14 + 14 = 56 cm. Area = 14 × 14 = 196 cm².
2. Perimeter 54 cm, area 182 cm²
Perimeter = 14 + 13 + 14 + 13 = 54 cm. Area = 14 × 13 = 182 cm².
3. Perimeter 50 cm, area 150 cm²
Perimeter = 15 + 10 + 15 + 10 = 50 cm. Area = 15 × 10 = 150 cm².
4. Perimeter 36 cm, area 80 cm²
Perimeter = 10 + 8 + 10 + 8 = 36 cm. Area = 10 × 8 = 80 cm².
5. 55 cm²
Area = ½ × base × height. ½ × 22 × 5 = 55 cm².
6. 4 cm²
Area = ½ × base × height. ½ × 4 × 2 = 4 cm².
7. 40 cm²
Area = ½ × base × height. ½ × 10 × 8 = 40 cm².
8. 156 cm²
Area = ½ × base × height. ½ × 24 × 13 = 156 cm².
9. Area 452.4 cm², circumference 75.4 cm
Area = πr² = π × 12² = 452.4 cm². Circumference = 2πr = 2 × π × 12 = 75.4 cm.
10. Area 50.3 cm², circumference 25.1 cm
Area = πr² = π × 4² = 50.3 cm². Circumference = 2πr = 2 × π × 4 = 25.1 cm.
11. Area 153.9 cm², circumference 44 cm
Area = πr² = π × 7² = 153.9 cm². Circumference = 2πr = 2 × π × 7 = 44 cm.
12. Area 380.1 cm², circumference 69.1 cm
Area = πr² = π × 11² = 380.1 cm². Circumference = 2πr = 2 × π × 11 = 69.1 cm.
Worked examples
A rectangle is 2 cm by 9 cm. Find its perimeter and area.
- Perimeter = 2 + 9 + 2 + 9 = 22 cm.
- Area = 2 × 9 = 18 cm².
- Answer: Perimeter 22 cm, area 18 cm²
A triangle has base 4 cm and height 14 cm. Find its area.
- Area = ½ × base × height.
- ½ × 4 × 14 = 28 cm².
- Answer: 28 cm²
Find the area and circumference of a circle with radius 2 cm (to 1 d.p.).
- Area = πr² = π × 2² = 12.6 cm².
- Circumference = 2πr = 2 × π × 2 = 12.6 cm.
- Answer: Area 12.6 cm², circumference 12.6 cm

Common mistakes
What learners typically get wrong, and how to fix it.
Mixes up area and perimeter.
Correction: Perimeter is a fence (around), area is grass (inside).
Uses the slanted side as the height of a triangle.
Correction: Height must be at right angles to the base.
Teacher tips
- · Draw shapes on squared paper and count squares first.
Parent tips
- · Measure a room and work out how much carpet you'd need.
Real-life applications
- · Carpeting a room, fencing a garden.
