  1. A rectangular evidence tarp is 12 feet by 5 feet. What is the length of its diagonal?

    Answer: 13 feet

    Using the Pythagorean theorem: √(12² + 5²) = √169 = 13 feet.

  2. A patrol zone is 0.5 miles by 0.5 miles. What is its area in square miles?

    Answer: 0.25 square miles

    Area = 0.5 × 0.5 = 0.25 square miles.

  3. A rectangular room measures 240 inches by 120 inches. What is its area in square feet? (12 inches = 1 foot)

    Answer: 200 square feet

    Convert to feet: 20 ft × 10 ft = 200 square feet.

  4. A trapezoidal lot has parallel sides of 10 ft and 14 ft and a height of 6 ft. What is its area?

    Answer: 72 square feet

    Area = ½ × (10 + 14) × 6 = ½ × 24 × 6 = 72 square feet.

  5. If the side of a square search area is doubled, how does its area change?

    Answer: It becomes 4 times larger

    Area scales with the square of the side, so doubling the side multiplies the area by 4.

  6. A rectangular field is 40 ft by 25 ft. A path 5 ft wide runs along one 40-ft side. What is the path's area?

    Answer: 200 square feet

    Path area = 40 × 5 = 200 square feet.

  7. A circular cordon must be 50 feet around (circumference). Using 3.14 for pi, what is its approximate radius?

    Answer: About 7.96 feet

    Radius = circumference ÷ (2 × pi) = 50 ÷ 6.28 ≈ 7.96 feet.
