- 60 square meters
- 30 square meters (Correct answer)
- 16 square meters
- 120 square meters
Correct answer: 30 square meters
Area of a triangle = ½ × base × height = ½ × 10 × 6 = 30 square meters.
Question 2: A rectangular box is 5 cm long, 3 cm wide, and 4 cm tall. What is its volume?
- 12 cubic cm
- 47 cubic cm
- 60 cubic cm (Correct answer)
- 24 cubic cm
Correct answer: 60 cubic cm
Volume of a rectangular prism = length × width × height = 5 × 3 × 4 = 60 cubic cm.
Question 3: An angle that measures more than 90° but less than 180° is called:
- Acute angle
- Right angle
- Obtuse angle (Correct answer)
- Straight angle
Correct answer: Obtuse angle
An obtuse angle measures between 90° and 180°.
Question 4: How many square inches are in 1 square foot?
- 12 square inches
- 24 square inches
- 36 square inches
- 144 square inches (Correct answer)
Correct answer: 144 square inches
Since 1 foot = 12 inches, 1 square foot = 12 × 12 = 144 square inches.
Question 5: A polygon with 6 sides is called a:
- Pentagon
- Heptagon
- Hexagon (Correct answer)

- 108 square yards
- 12 square yards (Correct answer)
- 36 square yards
- 18 square yards
Correct answer: 12 square yards
Convert to yards first: 9 ft = 3 yd, 12 ft = 4 yd; area = 3 × 4 = 12 square yards.
Question 7: A line segment drawn from the center of a circle to any point on the circle is called the:
- Chord
- Diameter
