Question

Medians of ΔABC intersect at G. If ar (ΔABC) = 27 cm², then ar (ΔBGC) =

(a) 6 cm²

(b) 9 cm²

(c) 12 cm²

(d) 18 cm²

Solution

Given: (1) Median of ΔABC meet at G.

(2) Area of ΔABC = 27 cm²

To find: Area of ΔBCG.

We know that the medians of the triangle divides each other in the ratio of 2:1

Hence,

Hence the correct answer is option (b).
