Show answers and working
1. Perimeter 42 cm, area 98 cm²
Perimeter = 14 + 7 + 14 + 7 = 42 cm. Area = 14 × 7 = 98 cm².
2. Perimeter 60 cm, area 225 cm²
Perimeter = 15 + 15 + 15 + 15 = 60 cm. Area = 15 × 15 = 225 cm².
3. Perimeter 36 cm, area 80 cm²
Perimeter = 8 + 10 + 8 + 10 = 36 cm. Area = 8 × 10 = 80 cm².
4. Perimeter 28 cm, area 49 cm²
Perimeter = 7 + 7 + 7 + 7 = 28 cm. Area = 7 × 7 = 49 cm².
5. 63 cm²
Area = ½ × base × height. ½ × 18 × 7 = 63 cm².
6. 120 cm²
Area = ½ × base × height. ½ × 30 × 8 = 120 cm².
7. 104 cm²
Area = ½ × base × height. ½ × 16 × 13 = 104 cm².
8. 63 cm²
Area = ½ × base × height. ½ × 14 × 9 = 63 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 314.2 cm², circumference 62.8 cm
Area = πr² = π × 10² = 314.2 cm². Circumference = 2πr = 2 × π × 10 = 62.8 cm.
11. Area 78.5 cm², circumference 31.4 cm
Area = πr² = π × 5² = 78.5 cm². Circumference = 2πr = 2 × π × 5 = 31.4 cm.
12. Area 153.9 cm², circumference 44 cm
Area = πr² = π × 7² = 153.9 cm². Circumference = 2πr = 2 × π × 7 = 44 cm.
Worked examples
A rectangle is 8 cm by 11 cm. Find its perimeter and area.
- Perimeter = 8 + 11 + 8 + 11 = 38 cm.
- Area = 8 × 11 = 88 cm².
- Answer: Perimeter 38 cm, area 88 cm²
A triangle has base 12 cm and height 11 cm. Find its area.
- Area = ½ × base × height.
- ½ × 12 × 11 = 66 cm².
- Answer: 66 cm²
Find the area and circumference of a circle with radius 11 cm (to 1 d.p.).
- Area = πr² = π × 11² = 380.1 cm².
- Circumference = 2πr = 2 × π × 11 = 69.1 cm.
- Answer: Area 380.1 cm², circumference 69.1 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.
