My question is from Projection of Line Inclined to one Plane and Parallel to other in chapter Projection of Lines of Engineering Drawing

Answer 1

Right answer is (b) 12 cm

Easy explanation: The front view of line on or parallel to vertical plane gives the actual length. The top view of line on or parallel to horizontal plane gives the actual length. The side view of line on or parallel to the profile plane gives the actual length.
