</h2>
Step-by-step explanation:
Given a triangle ABC with vertices A(2,1),B(12,2) and C(12,8)
The area of a triangle is=
=
= = 54 square units
The length of AC =
=
= units
Let the perpendicular distance from B to AC be = x
According To Problem
⇔ units
Therefore the perpendicular distance from B to AC is =
