ParaPro Geometry and Measurement 4 — Questions and Answers
Question 1: A rectangular garden measures 12 feet by 8 feet. What is the perimeter of the garden?
- 20 feet
- 40 feet (Correct answer)
- 96 feet
- 48 feet
Correct answer: 40 feet
Perimeter of a rectangle = 2(length + width) = 2(12 + 8) = 2(20) = 40 feet.
Question 2: Which of the following is a property of a right triangle?
- All three angles are equal
- One angle measures exactly 90° (Correct answer)
- All sides are equal length
- Two angles measure 90°
Correct answer: One angle measures exactly 90°
A right triangle has exactly one angle that measures 90 degrees.
Question 3: A circle has a radius of 5 cm. What is its diameter?
- 5 cm
- 15 cm
- 10 cm (Correct answer)
- 25 cm
Correct answer: 10 cm
The diameter equals twice the radius, so diameter = 2 × 5 = 10 cm.
Question 4: What is the volume of a cube with side length 4 inches?
- 16 cubic inches
- 24 cubic inches
- 48 cubic inches
- 64 cubic inches (Correct answer)
Correct answer: 64 cubic inches
Volume of a cube = side³ = 4³ = 4 × 4 × 4 = 64 cubic inches.
Question 5: A student measures a hallway and finds it is 15 yards long. How many feet is that?
- 5 feet
- 30 feet
- 45 feet (Correct answer)
- 180 feet
Correct answer: 45 feet
Since 1 yard = 3 feet, 15 yards × 3 = 45 feet.
Question 6: Two lines that never intersect and are always the same distance apart are called:
- Perpendicular lines
- Intersecting lines
- Parallel lines (Correct answer)
- Diagonal lines
Correct answer: Parallel lines
Parallel lines run in the same direction and never meet, maintaining a constant distance.
Question 7: A triangle has angles measuring 45°, 90°, and what third angle?
- 45° (Correct answer)
- 90°
- 135°
- 60°
Correct answer: 45°
The sum of angles in a triangle is 180°, so the third angle = 180° − 45° − 90° = 45°.
