Triangle ABC formed by two vectors a = ( 2, 10, 25 ) and b = ( 5, 4, -2 ) attached at a point A.

The area of the triangle is (81 root 5) / 2

And I need to find the length of the height AM (AM perpendicular to BC and the point M belongs to the line BC).

Don't know where to start!

2. Relevant equations

Area = 0.5 *h *b
