Question
If G is the centroid and AD, BE, CF are three medians of
∆ABCwith area 24 cm 2 , then the area of ∆CGD is?Solution
Meeting point of all medians AD, BE , CF is called as centroid. Always remember that, if G is centroid in ∆ ABC, In ∆ ABC, area of ∆ AGF = area of ∆ AGE = area of ∆ BGD = area of ∆BGF = area of ∆CGE = area of ∆CGD = 1/6th of the area of ∆ABC So area of ∆CGD = 1/6 th of area of ∆ABC = 1/6 × 24 = 4 cm 2
