In triangle ABC, D, BE and CF are medians and G is the centroid of the triangle. If the area of the triangle DGC is 20 cm2, then the area of triangle AGF + the area of triangle BGF is equal to:
Answer & explanation
Correct answer: option 4
We know that,
Area of triangles AGF, AGE, DGB, DGC, EGC and FGB are equal.
∆ DGC = 20 cm2
∆ AGF = ∆ BGF = 20 cm2
∆ AGF + ∆ BGF = 20 + 20 = 40 cm2
