Question:

In an equilateral triangle ABC, P is the centroid of this triangle. Side of ΔABC is $16\sqrt{3}$ cm. What is the distance of point P from side BC ?

Options:

8 cm

12 cm

9 cm

10 cm

Correct Answer:

8 cm

Explanation:

Height = AD = \(\frac{\sqrt {3}}{2}\) × Side

= Height = \(\frac{\sqrt {3}}{2}\) × 16√3

= AD = 24 cm

= AP : PD = 2 : 1

Let, AP = 2m

PD = m, AD = 3m

= 3m = 24

= m = 8
