We use the curved mirror formulae to get the image distance.:

1/f=1/v+1/u

V is object distance and u is image distance.

F is the focal length.

Substituting the values :1/15=1/25+1/u

1/u=1/15-1/25=5-3/75=2/75

U=75/2=37.5cm

We use the object distance and the image distance to get the magnification.

M=37.5/25=×1.5

The image size =1.5×7=10.5cm

The image is real.
