(d) 0 cm

I have been asked this question in my homework.

Asked question is from Projection of Planes Parallel to one of the Reference Plane topic in portion Projection of Planes of Engineering Drawing

Answer 1

The correct answer is (b) 14.14 cm

To elaborate: Given the square is parallel to vertical plane ad diagonal is perpendicular to xy reference plane the top view and side gives a line and both of same length which is equal to diagonal length L= 2 x √(5^2+5^2 ) = 14.14 cm.
