Show answers and working
1. Perimeter 38 cm, area 90 cm²
Perimeter = 10 + 9 + 10 + 9 = 38 cm. Area = 10 × 9 = 90 cm².
2. Perimeter 8 cm, area 4 cm²
Perimeter = 2 + 2 + 2 + 2 = 8 cm. Area = 2 × 2 = 4 cm².
3. Perimeter 52 cm, area 165 cm²
Perimeter = 11 + 15 + 11 + 15 = 52 cm. Area = 11 × 15 = 165 cm².
4. Perimeter 24 cm, area 36 cm²
Perimeter = 6 + 6 + 6 + 6 = 24 cm. Area = 6 × 6 = 36 cm².
5. 26 cm²
Area = ½ × base × height. ½ × 26 × 2 = 26 cm².
6. 99 cm²
Area = ½ × base × height. ½ × 18 × 11 = 99 cm².
7. 56 cm²
Area = ½ × base × height. ½ × 14 × 8 = 56 cm².
8. 60 cm²
Area = ½ × base × height. ½ × 8 × 15 = 60 cm².
9. Area 380.1 cm², circumference 69.1 cm
Area = πr² = π × 11² = 380.1 cm². Circumference = 2πr = 2 × π × 11 = 69.1 cm.
10. Area 78.5 cm², circumference 31.4 cm
Area = πr² = π × 5² = 78.5 cm². Circumference = 2πr = 2 × π × 5 = 31.4 cm.
11. Area 201.1 cm², circumference 50.3 cm
Area = πr² = π × 8² = 201.1 cm². Circumference = 2πr = 2 × π × 8 = 50.3 cm.
12. Area 12.6 cm², circumference 12.6 cm
Area = πr² = π × 2² = 12.6 cm². Circumference = 2πr = 2 × π × 2 = 12.6 cm.
Worked examples
A rectangle is 11 cm by 8 cm. Find its perimeter and area.
- Perimeter = 11 + 8 + 11 + 8 = 38 cm.
- Area = 11 × 8 = 88 cm².
- Answer: Perimeter 38 cm, area 88 cm²
A triangle has base 4 cm and height 3 cm. Find its area.
- Area = ½ × base × height.
- ½ × 4 × 3 = 6 cm².
- Answer: 6 cm²
Find the area and circumference of a circle with radius 9 cm (to 1 d.p.).
- Area = πr² = π × 9² = 254.5 cm².
- Circumference = 2πr = 2 × π × 9 = 56.5 cm.
- Answer: Area 254.5 cm², circumference 56.5 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.
