    A 6 cm² Correct Answer Incorrect Answer

    C 84 cm² Correct Answer Incorrect Answer
    D 210 cm² Correct Answer Incorrect Answer

    Solution

    As sides 7, 24 & 25 is a Pythagoras triplet means 72 + 242 = 252 ; this is a right angle triangle. So area of this triangle = 1/2 × base × height = (1/2) × 7 × 24 = 84 cm 2
