A rectangular swimming pool is 25 meters long and 10 meters wide. What is the perimeter of the pool?
Answer: 70 meters
Perimeter of a rectangle = 2(length + width) = 2(25 + 10) = 2(35) = 70 meters.
A triangle has sides measuring 7 cm, 7 cm, and 10 cm. What type of triangle is this?
Answer: Isosceles
An isosceles triangle has exactly two sides of equal length, which matches 7 cm, 7 cm, and 10 cm.
What is the volume of a rectangular box that is 5 inches long, 4 inches wide, and 3 inches tall?
Answer: 60 cubic inches
Volume = length × width × height = 5 × 4 × 3 = 60 cubic inches.
Two lines intersect forming angles. One angle measures 65°. What is the measure of the angle directly across from it (vertical angle)?
Answer: 65°
Vertical angles are congruent (equal), so the opposite angle also measures 65°.
A circle has a diameter of 14 cm. What is its circumference? (Use π ≈ 3.14)
Answer: 43.96 cm
Circumference = π × diameter = 3.14 × 14 = 43.96 cm.
On a coordinate plane, point A is at (2, 3) and point B is at (2, -5). What is the distance between them?
Answer: 8 units
Since the x-coordinates are the same, the distance is |3 − (−5)| = |8| = 8 units.
A trapezoid has bases of 8 cm and 12 cm and a height of 5 cm. What is its area?
Answer: 50 cm²
Area of a trapezoid = ½ × (b₁ + b₂) × h = ½ × (8 + 12) × 5 = ½ × 100 = 50 cm².
