  1. A rectangular garden is 8.5 meters long and 4 meters wide. What is its area?

    Answer: 34 m²

    Area of a rectangle = length × width = 8.5 × 4 = 34 m².

  2. How many millimeters are in 3.7 centimeters?

    Answer: 37 mm

    1 cm = 10 mm, so 3.7 cm × 10 = 37 mm.

  3. A triangle has a base of 10 inches and a height of 6 inches. What is its area?

    Answer: 30 in²

    Area of a triangle = ½ × base × height = ½ × 10 × 6 = 30 in².

  4. A room measures 12 feet by 15 feet. How many square yards of carpet are needed to cover it?

    Answer: 20 yd²

    180 ft² ÷ 9 (since 1 yd² = 9 ft²) = 20 yd².

  5. Which unit is most appropriate for measuring the distance between two cities?

    Answer: Kilometers

    Kilometers are used for large distances such as between cities.

  6. A square tile has sides of 20 cm. What is its area in square meters?

    Answer: 0.04 m²

    20 cm = 0.2 m, so area = 0.2 × 0.2 = 0.04 m².

  7. A rectangular field is 250 meters long and 80 meters wide. What is the perimeter?

    Answer: 660 m

    Perimeter = 2 × (length + width) = 2 × (250 + 80) = 2 × 330 = 660 m.
