Answer 2

$\huge\red{A}\huge\green{N}\huge\pink{S}\huge\blue{W}\huge\purple{E}\huge\orange{R}$

u=-6cm

f=12cm

1/f=1/v+1/u

1/12=1/v-1/6

1/v=1/6+1/12

1/v=3/12=1/4

v=4cm

image is formed 4cm beyond the mirror

since the mirror used is convex image is erect and virtual

height of image/height of object=-v/u

H' H / = - / -4 / 6 = 2/3

H'=2/3H
