Question

in the adjoining figure Gis is centroid of triangle PQR if pt = 6cm, QA = 9cm, BG = 5cm, find QG, RB, PG
​

Answer 1

The point of concurrence of medians of a triangle divides each median in the ratio 2:1.

Let us suppose the length of PG and GT be 2x and x.

Therefore, the value of x is 2.5

Now, PG=2x

=2(2.5)

=5units

Now, PT=PG+GT$

=5+2.5

=7.5units

Hence, the length od PG and GT is 5 and 7.5 respectively.
