Suppose the medians BD and CE of a triangle ABC intersect at a point O. If area of triangle ABC is 108 sq. cm., then, the area of the triangle EOD, in sq. cm., is
Correct Answer: 9
Area of ABD : Area of BDC = 1:1
Therefore, area of ABD = 54
Area of ADE : Area of EDB = 1:1
Therefore, area of ADE = 27
O is the centroid and it divides the medians in the ratio of 2:1
Area of BEO : Area of EOD = 2:1
Area of EOD = 9

Why the answer is not 12 as the triangles can be equally divided using the centroid.
Now each triangle has 36cm2. And the triangle are in the ratio of 2:1, which makes the required area EOD as 12cm2
