As per your syllabus, Math, what is the formula for the AREA of a rectangle with length a and width b?

  1. a² + b²
  2. ab (length × width)
  3. 2(a + b)
  4. ½ab
Show answer and solution

Correct answer: B. ab (length × width)

Rectangle area = length × width = ab. The other options confuse it with perimeter, Pythagoras, or triangle area.

As per your syllabus, what is the formula for the AREA of a PARALLELOGRAM with base b and corresponding height h?

  1. b + h
  2. ½ × b × h
  3. b × h (base × perpendicular height)
  4. b²
Show answer and solution

Correct answer: C. b × h (base × perpendicular height)

Parallelogram area = base × height. The other options confuse it with perimeter, triangle area, or square area.

As per your syllabus, what is the formula for the AREA of a TRIANGLE with base b and corresponding height h?

  1. ½ × b × h
  2. b × h
  3. b + h
  4. b² + h²
Show answer and solution

Correct answer: A. ½ × b × h

Triangle area = ½ × base × height (half of the parallelogram formed by doubling it). The other options misstate.
