  1. A farmer has a field shaped like a right triangle with legs of 30 m and 40 m. What is the area?

    Answer: 600 m²

    Area = ½ × base × height = ½ × 30 × 40 = 600 m².

  2. How many fluid ounces are in 4 cups?

    Answer: 32 fl oz

    1 cup = 8 fl oz, so 4 cups × 8 = 32 fl oz.

  3. A rectangular piece of land is 0.5 km long and 0.3 km wide. What is its area in square meters?

    Answer: 150,000 m²

    0.5 km = 500 m and 0.3 km = 300 m; area = 500 × 300 = 150,000 m².

  4. A thermometer reads 86°F. What is the equivalent temperature in Celsius? (C = (F − 32) × 5/9)

    Answer: 30°C

    (86 − 32) × 5/9 = 54 × 5/9 = 30°C.

  5. A square has a perimeter of 52 cm. What is its area?

    Answer: 169 cm²

    Side = 52 ÷ 4 = 13 cm; area = 13² = 169 cm².

  6. A box has dimensions 50 cm × 30 cm × 20 cm. What is its volume in liters? (1 L = 1,000 cm³)

    Answer: 30 L

    Volume = 50 × 30 × 20 = 30,000 cm³; 30,000 ÷ 1,000 = 30 L.

  7. A map has a scale of 1:50,000. A road measures 4 cm on the map. How long is the actual road in kilometers?

    Answer: 2 km

    4 cm × 50,000 = 200,000 cm = 2,000 m = 2 km.
