Tell this to me

Dear Student
Height (h) = 4cm
Since it is a concave mirror therefore f = -15cm
Object distance (u) = -25cm
v = ?
h' = ?
By mirror formula...
1/v + 1/u = 1/f
By putting the above values, we get
1/v = -1/15+1/25 
v = -37.5cm
Also, h'/h = -v/u
So we get h' = -6cm
Therefore, the image is real, inverted and magnified...
