    A 14 cm² Correct Answer Incorrect Answer
    B 10 cm² Correct Answer Incorrect Answer
    C 12cm² Correct Answer Incorrect Answer
    D 16 cm² Correct Answer Incorrect Answer

    Solution

    Meeting point of all medians is called as centroid. Always remember that if G is centroid in ∆ ABC then area of ∆ AGB = area of ∆ BGC = area of ∆ AGC = 1/3 of ∆ ABC so area of the ∆ AGC = 1/3 of 30 = 10 cm²
