    Question

    If the area of ∆ ABC is 33 cm2 & G is the

    centroid of ∆ ABC.then the area of the ∆ BGC?
    A 6cm² Correct Answer Incorrect Answer
    B 8cm² Correct Answer Incorrect Answer
    C 12cm² Correct Answer Incorrect Answer
    D 11cm² 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  ∆  BGC = 1/3 of 33 =  11  cm²
