Answer:
Distance between the mirror and the persons image= 9m
distance the person moved toward the plane mirror=
3m
The distance between the person and his image=
•The distance between the image of that person and the person is 2×the distance between the person and the mirror as the distance between the image and the object in plane mirrors is equal
so, 9-3=6
6×6=36
so the distance between the person and his image=36m
