∠A of ΔABC is a right angle. AD is perpendicular on BC. If BC = 14 and BD = 5 cm, then measure of AD is:

A. $$\sqrt 5 $$ cm

B. $$3\sqrt 5 $$ cm

C. $$3.5\sqrt 5 $$  cm

D. $$2\sqrt 5 $$ cm

Answer: Option B

Solution(By Examveda Team)

AD² = BD × DC
AD² = 5 × 9
AD = $$\sqrt {45} $$
AD = $$3\sqrt 5 $$  cm
