Show answers and working
  1. 1. Perimeter 52 cm, area 168 cm²

    Perimeter = 12 + 14 + 12 + 14 = 52 cm. Area = 12 × 14 = 168 cm².

  2. 2. Perimeter 54 cm, area 182 cm²

    Perimeter = 13 + 14 + 13 + 14 = 54 cm. Area = 13 × 14 = 182 cm².

  3. 3. Perimeter 32 cm, area 39 cm²

    Perimeter = 3 + 13 + 3 + 13 = 32 cm. Area = 3 × 13 = 39 cm².

  4. 4. Perimeter 36 cm, area 56 cm²

    Perimeter = 4 + 14 + 4 + 14 = 36 cm. Area = 4 × 14 = 56 cm².

  5. 5. 72 cm²

    Area = ½ × base × height. ½ × 18 × 8 = 72 cm².

  6. 6. 70 cm²

    Area = ½ × base × height. ½ × 28 × 5 = 70 cm².

  7. 7. 56 cm²

    Area = ½ × base × height. ½ × 28 × 4 = 56 cm².

  8. 8. 21 cm²

    Area = ½ × base × height. ½ × 6 × 7 = 21 cm².

  9. 9. Area 78.5 cm², circumference 31.4 cm

    Area = πr² = π × 5² = 78.5 cm². Circumference = 2πr = 2 × π × 5 = 31.4 cm.

  10. 10. Area 28.3 cm², circumference 18.8 cm

    Area = πr² = π × 3² = 28.3 cm². Circumference = 2πr = 2 × π × 3 = 18.8 cm.

  11. 11. Area 12.6 cm², circumference 12.6 cm

    Area = πr² = π × 2² = 12.6 cm². Circumference = 2πr = 2 × π × 2 = 12.6 cm.

  12. 12. Area 452.4 cm², circumference 75.4 cm

    Area = πr² = π × 12² = 452.4 cm². Circumference = 2πr = 2 × π × 12 = 75.4 cm.

Worked examples

Easy example

A rectangle is 8 cm by 7 cm. Find its perimeter and area.

  1. Perimeter = 8 + 7 + 8 + 7 = 30 cm.
  2. Area = 8 × 7 = 56 cm².
  3. Answer: Perimeter 30 cm, area 56 cm²
Medium example

A triangle has base 20 cm and height 3 cm. Find its area.

  1. Area = ½ × base × height.
  2. ½ × 20 × 3 = 30 cm².
  3. Answer: 30 cm²
Hard example

Find the area and circumference of a circle with radius 10 cm (to 1 d.p.).

  1. Area = πr² = π × 10² = 314.2 cm².
  2. Circumference = 2πr = 2 × π × 10 = 62.8 cm.
  3. Answer: Area 314.2 cm², circumference 62.8 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.
