ILEARN Mathematics Standards 2 — Questions and Answers
Question 1: A rectangle has a length of 14 cm and a width of 9 cm. What is the area of the rectangle?
- 23 cm²
- 46 cm²
- 126 cm² (Correct answer)
- 252 cm²
Correct answer: 126 cm²
Area of a rectangle = length × width = 14 × 9 = 126 cm².
Question 2: Which of the following is equivalent to 3/4?
- 0.34
- 0.75 (Correct answer)
- 0.43
- 0.57
Correct answer: 0.75
3 ÷ 4 = 0.75, so 3/4 = 0.75.
Question 3: If x + 7 = 15, what is the value of x?
- 6
- 7
- 8 (Correct answer)
- 22
Correct answer: 8
Subtract 7 from both sides: x = 15 − 7 = 8.
Question 4: A bag has 3 red marbles, 5 blue marbles, and 2 green marbles. What is the probability of randomly picking a blue marble?
- 1/2
- 1/5
- 3/10
- 5/10 (Correct answer)
Correct answer: 5/10
There are 5 blue out of 10 total marbles, so the probability is 5/10 = 1/2.
Question 5: What is the value of 2³ × 4?
- 24
- 32 (Correct answer)
- 48
- 64
Correct answer: 32
2³ = 8, and 8 × 4 = 32.
Question 6: A number line shows point P at −3 and point Q at 5. What is the distance between the two points?
- 2
- 3
- 8 (Correct answer)
- 15
Correct answer: 8
Distance = |5 − (−3)| = |5 + 3| = 8.
Question 7: Which expression represents 'twice the sum of a number n and 6'?
- 2n + 6
- 2(n + 6) (Correct answer)
- n + 12
- 2n + 12
Correct answer: 2(n + 6)
Twice the sum of n and 6 is written as 2(n + 6).
