Verified Answer
ABC is right-angled at A. ADis perpendicular to BC,AB=5cm,BC=13cm and ...
∆ABC is right - angled at A. 
so, BC is definitely hypotenuse.
let AB is base and AC is altitude of ∆ABC.
given, AB = 5cm , BC = 13cm and AC = 12cm 

now, area of triangle ∆ABC = 1/2 x base x altitude 
= 1/2 x length of AB x length of AC 
= 1/2 x 5cm x 12cm = 30 cm^2 
hence, area of ∆ABC = 30cm^2

area of ∆ABC = 1/2 x length of AB x length of AC = 1/2 x length of BC x length of AD
=> 5cm x 12cm = 13cm x length of AD 
=> 60/13 = length of AD 
hence, length of AD = 60/13 cm
