I really need help with this problem. Give me at least a hint on how to solve it.(adsbygoogle = window.adsbygoogle || []).push({});

You are standing in front of a lens that projects an image of you onto a wall 2.00m on the other side of the lens. This image is three times your height.

A)

How far are you from the lens?

B)

What is the focal length of the lens?

Your help will be much appreciated :'0
