Question

    Find the area of triangle having sides 5 m, 6 m, and 9 m.

    A 30 m² Correct Answer Incorrect Answer
    B 6√35 m² Correct Answer Incorrect Answer
    C 14√5 m² Correct Answer Incorrect Answer
    D 6√5 m² Correct Answer Incorrect Answer

    Solution

    Here s = semi perimeter = (5 + 6 + 9)/2 = 10 m So area of this triangle = √(10 (10 - 5)(10 - 6)(10 - 9))  = √(10 × 5 × 4 × 1) = 30 m 2
