Hi Phower Power! Welcome to PF! :smile:
… I don't know how to set up the equation int his kind of situation.
I don't get it …

I assume you do know how to set it up in some other situation? :confused:

Just do the same, and convert "The image is half the height of the object, inverted, and real" into an equation also.
