Math Math Geometry and Measurement 1 — Questions and Answers
Question 1: What is the area of a triangle with a base of 10 cm and a height of 6 cm?
- 30 cm² (Correct answer)
- 60 cm²
- 16 cm²
- 120 cm²
Correct answer: 30 cm²
Area of a triangle = ½ × base × height = ½ × 10 × 6 = 30 cm².
Question 2: What is the circumference of a circle with a radius of 7 cm? (Use π ≈ 3.14)
- 43.96 cm (Correct answer)
- 21.98 cm
- 153.86 cm
- 49 cm
Correct answer: 43.96 cm
Circumference = 2πr = 2 × 3.14 × 7 = 43.96 cm.
Question 3: How many degrees are in the interior angles of a triangle?
- 180° (Correct answer)
- 360°
- 270°
- 90°
Correct answer: 180°
The sum of interior angles of any triangle is always 180°.
Question 4: A rectangle has a length of 12 m and a width of 5 m. What is its perimeter?
- 34 m (Correct answer)
- 60 m
- 17 m
- 24 m
Correct answer: 34 m
Perimeter = 2(length + width) = 2(12 + 5) = 2 × 17 = 34 m.
Question 5: What is the volume of a cube with side length 4 cm?
- 64 cm³ (Correct answer)
- 16 cm³
- 48 cm³
- 96 cm³
Correct answer: 64 cm³
Volume of a cube = side³ = 4³ = 64 cm³.
Question 6: Two angles of a triangle measure 55° and 75°. What is the third angle?
- 50° (Correct answer)
- 40°
- 60°
- 70°
Correct answer: 50°
Third angle = 180° − 55° − 75° = 50°.
