I have a physic homework on concave and convex lens and how the light refracts when it goes through it. And I'm stuck on the part where I have to find the height of the object. The only information on the question is that it has the magnification factor of 2.3x and that the object is 3m away from the lens. Thank you so much if you can tell me how to solve this. I need to draw a diagram on it so I need it asap!!

You have found the distance of the image Omi, but the question asks for the height of the object.  There isn't enough information in the question to determine this (other than it will be 2.3 times smaller than the image!).
