Solution

Answer is correct. The image formed in a plane mirror is as far behind the mirror as the object is in front of it, i.e. the distance between the object and the mirror (u) is the same as the distance between the mirror and the image (v).

u = v = 2 m

Distance between object (boy) and the image is u + v = 2m + 2m = 4m.
