Answer»

SOLUTION :(i) Ratio of height of the image to height of the OBJECT is magnification.
M(mirror) `=h^(1)//h=-v//u`
h= Height of object
`h^(1)=` Height of image
v=image of distance
u= Object distance
(ii) It MEANS image FORMED is two times of size of object and the image formed is INVERTED, formed in front of the lens.
