Here is the question which I am struggling on, please help me!

Question: You are examining a recent acquisition for your stamp collection through a hand-held reading glass (a converging lens).

Question 1: Determine the focal length of the lens, if when the reading glass is 2.82 cm from the stamp the image of the stamp appears to be five times the size of the actual stamp.

Please use as much detail as possible in answer.
