____m to the left of the lens?

Have you seen an equation that looks something like

1/Do + I/Df = 1/f ?

Well, you have now.

Di = image distance = 3.3 m
f = focal length = 0.19 m

Solve for Do (object distance) in meters

The object is close to the focal point. You have a highly magnified image
Okay, thanks!
You're welcome! Let me know if you have any other questions.
