QUESTION #58 Area of a Triangle in 3D Space
Let in a Delta ABC , the length of the side AC be 6, the vertex B be (1, 2, 3) and the vertices A, C lie on the line fracx - 63 = fracy - 72 = fracz - 7-2 . Then the area (in sq. units) of Delta ABC is :

QUESTION #68 Intersection of Lines in 3D Space
Let the line passing through the points (-1, 2, 1) and \parallel to the line fracx - 12 = fracy + 13 = fracz4 intersect the line fracx + 23 = fracy - 32 = fracz - 41 at the point P. Then the distance of P from the point Q(4, -5, 1) is :
