In ΔABC, AD is median and G is the point on AD such that AG : GD = 2 : 1, then area (ΔABG) : area (ΔABC) is equal to?
Answer & explanation
Correct answer: option 2
G is centroid
So, area of ΔABG = area of ΔBGC = area of ΔAGC
Let area of each Δ = 1 Unit2
area of ΔABC = ΔABG + area of ΔBGC + area of ΔAGC = 3
area of (ΔABG) : area of (ΔABC)
1 : 3
