AD is the median of triangle ABC. P is the centroid of triangle ABC. If AP = 14 cm, then what is the length of PD ?

14 cm 28 cm 21 cm 7 cm

7 cm

We know that, The centroid of the triangle divides each of its median in the ratio 2:1. AP = 14 cm \(\frac{AP}{PD}\) = \(\frac{1}{2}\)  \(\frac{14}{PD}\) = \(\frac{1}{2}\)  PD = \(\frac{14}{2}\) = 7cm
