  1. A square has a perimeter of 36 meters. What is the area of the square?

    Answer: 81 sq m

    Each side = 36 ÷ 4 = 9 m; Area = 9² = 81 square meters.

  2. In a right triangle, the two legs measure 6 ft and 8 ft. What is the length of the hypotenuse?

    Answer: 10 ft

    By the Pythagorean theorem: c = √(6² + 8²) = √(36 + 64) = √100 = 10 ft.

  3. Which of the following best describes a parallelogram?

    Answer: A quadrilateral with two pairs of parallel sides

    A parallelogram is defined as a quadrilateral in which both pairs of opposite sides are parallel.

  4. A trapezoid has parallel bases of 5 cm and 9 cm, and a height of 4 cm. What is its area?

    Answer: 28 cm²

    Area = ½ × (b₁ + b₂) × h = ½ × (5 + 9) × 4 = ½ × 14 × 4 = 28 cm².

  5. An angle measures 145°. What type of angle is it?

    Answer: Obtuse

    An obtuse angle measures greater than 90° and less than 180°.

  6. How many degrees are in the sum of the interior angles of any triangle?

    Answer: 180°

    The interior angles of any triangle always sum to exactly 180°.

  7. A scale drawing uses a scale of 1 inch = 5 feet. If a wall is 3.5 inches on the drawing, how long is the actual wall?

    Answer: 17.5 feet

    Actual length = 3.5 × 5 = 17.5 feet.
