The size of image can be calculated by using the magnification formula
I.e., m= -v/u = hi/ho

size of image can be calculated by
1.If magnification and size of object is given then
m=hi/ho
m×ho=hi
where m stands for magnification, hi stands for image size and ho stands for object size.
2.If image distance , object distance and ho is given then
-v/u = hi/ho
where v stands for image distance and u stands for object distance from the mirror.
Note:- if image distance and focal length or object distance and focal length is given the other can be found by using the mirror formula i.e.
1/f = 1/v + 1/u
