Step-by-step explanation:

a=5cm, b=12cm, c=13cm

=

=

Let A be the area of the given triangle, then

A =

=

= = 30 cm2

Let p be the length of the perpendicular from vertex D on the side BC, then

A =

2A = 13p

2 × 30 = 13P

Hence, length of perpendicular from the opposite vertex to the side whose length is 13 cm is cm.
