Question 1: A rectangular classroom is 30 feet long and 24 feet wide. What is the area of the classroom?
- 54 square feet
- 108 square feet
- 720 square feet (Correct answer)
- 600 square feet
Correct answer: 720 square feet
Area of a rectangle = length × width = 30 × 24 = 720 square feet.
Question 2: A student wants to find the perimeter of a square with a side length of 7 inches. What is the perimeter?
- 14 inches
- 21 inches
- 28 inches (Correct answer)
- 49 inches
Correct answer: 28 inches
The perimeter of a square = 4 × side = 4 × 7 = 28 inches.
Question 3: How many inches are in 3.5 feet?
- 36 inches
- 40 inches
- 42 inches (Correct answer)
- 48 inches
Correct answer: 42 inches
Since 1 foot = 12 inches, 3.5 × 12 = 42 inches.
Question 4: A triangle has a base of 10 cm and a height of 6 cm. What is its area?
- 60 square cm
- 30 square cm (Correct answer)
- 16 square cm
- 120 square cm
Correct answer: 30 square cm
Area of a triangle = ½ × base × height = ½ × 10 × 6 = 30 square cm.
Question 5: Which of the following best describes a right angle?
- An angle that measures exactly 180°
- An angle that measures exactly 45°
- An angle that measures exactly 90° (Correct answer)
- An angle that measures exactly 60°
Correct answer: An angle that measures exactly 90°
A right angle measures exactly 90 degrees, forming a perfect corner.
Question 6: A circle has a radius of 5 inches. What is the approximate circumference? (Use π ≈ 3.14)
- 15.7 inches
- 31.4 inches (Correct answer)
- 78.5 inches
- 25 inches
Correct answer: 31.4 inches
Circumference = 2πr = 2 × 3.14 × 5 = 31.4 inches.
Question 7: A paraprofessional needs to convert 2 yards into feet for a craft project. How many feet is 2 yards?
- 4 feet
- 6 feet (Correct answer)
