Answer

m = -v/u = hi/ho

     -4.5/-8 =  hi/3

        -13.5/-8  = hi

            1.68cm = hi

Therefore, height of image is 1.68cm

The question is wrong as concave mirror always produces enlarged virtual image and enlarged real image of an object. In this case height of object is 3cm and height of image is 1.68cm which is wrong.

Hope this helps!!

Cheers!!
