$\huge \purple{answer..}$

G I V E N..

➡ hight of the object = 5 cm

➡ object distance = - 20 cm

➡ hight of the object = h'

Magnification of the mirror ➡

V = 40 cm

So, the image is formed behind the mirror at a distance of 40 cm. The mirror is concave mirror.

Using mirror equation ➡

F = - 40 cm
