Primary 4 Mathematics Quiz - Measurement (Answer Key)

Total Marks: 40
Topic: Measurement

---

Section A (1 mark each)

1. 3040 m
   Method: 1 km = 1000 m, so 3 km = 3000 m. Add 40 m → 3040 m.
   Teaching note: Convert bigger unit to smaller by multiplying; then add remainder.

2. 2350 g
   Method: 1 kg = 1000 g, so 2 kg = 2000 g. Add 350 g → 2350 g.

3. 7.5 l
   Method: 1000 ml = 1 l, so 7500 ÷ 1000 = 7.5 l.
   Common mistake: writing 75 l (forgot decimal shift).

4. 1.2 m
   Method: 100 cm = 1 m, so 120 ÷ 100 = 1.2 m.

5. 5 l
   Method: 4.78 rounded to nearest whole: tenths digit 7 ≥ 5, round up to 5.

6. Equal
   Method: 0.9 kg = 900 g, so both are same.

7. 1200 g
   Method: 1.2 × 1000 = 1200 g.

8. 1500 ml
   Method: 1.5 × 1000 = 1500 ml.

9. 6.5 cm
   Method: 65 ÷ 10 = 6.5 cm.

10. 100 cm
    Method: 95 to nearest 10 → 100 (ones digit 5 rounds up).

Section B (2 marks each)

11. 255 cm
    Working: 5 m = 500 cm; 2 m 45 cm = 245 cm.
    500 − 245 = 255 cm.
    Marks: 1 for conversion, 1 for answer.

12. 2350 g
    Working: 3 kg 200 g = 3200 g.
    3200 − 850 = 2350 g.
    Marks: 1 conversion, 1 subtraction.

13. 8400 ml
    Working: 12 − 3.6 = 8.4 l.
    8.4 × 1000 = 8400 ml.

14. 46 cm
    Working: Perimeter = 2 × (length + breadth) = 2 × (14 + 9) = 2 × 23 = 46 cm.

15. 121 cm²
    Working: Area = side × side = 11 × 11 = 121 cm².

16. 400 m²
    Working: Area = length × breadth = 25 × 16 = 400 m².

---

Section C (3 marks each)

17. 126 cm²
    Working:
    Area A = 12 × 8 = 96 cm²
    Area B = 6 × 5 = 30 cm²
    Total = 96 + 30 = 126 cm²
    Marks: 1 for A, 1 for B, 1 for total.

18. 15 m
    Working: Breadth = Area ÷ Length = 450 ÷ 30 = 15 m.
    Marks: 1 formula, 1 division, 1 answer.

19. 30 cm
    Working: 2 m 40 cm = 240 cm.
    240 ÷ 8 = 30 cm.
    Marks: 1 conversion, 1 division, 1 answer.

20. 900 ml
    Working: 4.5 l = 4500 ml.
    4500 ÷ 5 = 900 ml.
    Marks: 1 conversion, 1 division, 1 answer.
