Question of The Day22-11-2021
In △ ABC, G is the centroid, AB = 12 cm, BC = 10 cm and CA = 14 cm, then what is the value (in cm) of GD?
Answer
Correct Answer : c ) 8 cm
Explanation :According to the question
AB = c = 12 cm, BC = a = 10 cm and CA = b = 14 cm
AD is the median
We know that
median=
Median=
⇒Median=
Since, ≅ 24
⇒Median==
⇒ 12 cm
Centroid divides Median in the ratio 2 : 1
⇒GD=
⇒ GD = 4 cm
Hence, (c) is the correct answer.
