How do you solve this problem?? I've attempted it so many times!?

A slide projector has a converging lens whose focal length is 131.00 mm. (a) How far (in meters) from the lens must the screen be located if a slide is placed 133.98 mm from the lens? If the slide measures 24.0 mm (height) x 36.0 mm (width), what are the magnitudes of the (b) width (in mm) and (c) height (in mm) of its image?
