KS2 SATs KS2 Mathematics 4 — Questions and Answers
Question 1: What is the formula for the area of a triangle?
- base × height
- ½ × base × height (Correct answer)
- base + height
- 2 × base × height
Correct answer: ½ × base × height
Area of a triangle = ½ × base × height. This is because a triangle is half of a rectangle with the same base and height.
Question 2: What is 300,000 + 40,000 + 700 + 60 + 3?
- 340,763 (Correct answer)
- 304,763
- 340,673
- 340,763
Correct answer: 340,763
Adding the place values: 300,000 + 40,000 = 340,000, + 700 = 340,700, + 60 = 340,760, + 3 = 340,763.
Question 3: What is the lowest common multiple (LCM) of 4 and 6?
- 2
- 12 (Correct answer)
- 24
- 6
Correct answer: 12
Multiples of 4: 4, 8, 12, 16... Multiples of 6: 6, 12, 18... The first number that appears in both lists is 12. So the LCM of 4 and 6 is 12.
Question 4: What is 15% of 200?
- 20
- 25
- 30 (Correct answer)
- 35
Correct answer: 30
15% = 10% + 5%. 10% of 200 = 20. 5% of 200 = 10. 20 + 10 = 30. So 15% of 200 is 30.
Question 5: What is the volume of a cuboid 5 cm × 3 cm × 2 cm?
- 10 cm³
- 30 cm³ (Correct answer)
- 16 cm³
- 25 cm³
Correct answer: 30 cm³
Volume of a cuboid = length × width × height = 5 × 3 × 2 = 30 cm³. Volume is measured in cubic units.
Question 6: A number is multiplied by itself and the answer is 144. What is the number?
- 11
- 12 (Correct answer)
- 13
- 14
Correct answer: 12
12 × 12 = 144, so the square root of 144 is 12. Knowing square numbers helps: 11² = 121, 12² = 144, 13² = 169.
