Show answers and working
1. Perimeter 30 cm, area 36 cm²
Perimeter = 3 + 12 + 3 + 12 = 30 cm. Area = 3 × 12 = 36 cm².
2. Perimeter 14 cm, area 12 cm²
Perimeter = 4 + 3 + 4 + 3 = 14 cm. Area = 4 × 3 = 12 cm².
3. Perimeter 22 cm, area 28 cm²
Perimeter = 7 + 4 + 7 + 4 = 22 cm. Area = 7 × 4 = 28 cm².
4. Perimeter 22 cm, area 18 cm²
Perimeter = 9 + 2 + 9 + 2 = 22 cm. Area = 9 × 2 = 18 cm².
5. 165 cm²
Area = ½ × base × height. ½ × 30 × 11 = 165 cm².
6. 40 cm²
Area = ½ × base × height. ½ × 16 × 5 = 40 cm².
7. 130 cm²
Area = ½ × base × height. ½ × 20 × 13 = 130 cm².
8. 75 cm²
Area = ½ × base × height. ½ × 10 × 15 = 75 cm².
9. Area 28.3 cm², circumference 18.8 cm
Area = πr² = π × 3² = 28.3 cm². Circumference = 2πr = 2 × π × 3 = 18.8 cm.
10. Area 254.5 cm², circumference 56.5 cm
Area = πr² = π × 9² = 254.5 cm². Circumference = 2πr = 2 × π × 9 = 56.5 cm.
11. Area 113.1 cm², circumference 37.7 cm
Area = πr² = π × 6² = 113.1 cm². Circumference = 2πr = 2 × π × 6 = 37.7 cm.
12. Area 314.2 cm², circumference 62.8 cm
Area = πr² = π × 10² = 314.2 cm². Circumference = 2πr = 2 × π × 10 = 62.8 cm.
Worked examples
A rectangle is 7 cm by 12 cm. Find its perimeter and area.
- Perimeter = 7 + 12 + 7 + 12 = 38 cm.
- Area = 7 × 12 = 84 cm².
- Answer: Perimeter 38 cm, area 84 cm²
A triangle has base 14 cm and height 3 cm. Find its area.
- Area = ½ × base × height.
- ½ × 14 × 3 = 21 cm².
- Answer: 21 cm²
Find the area and circumference of a circle with radius 7 cm (to 1 d.p.).
- Area = πr² = π × 7² = 153.9 cm².
- Circumference = 2πr = 2 × π × 7 = 44 cm.
- Answer: Area 153.9 cm², circumference 44 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.
