How to i work out the length of a plant cell?

I have recently been given some science homework and i don't know how to work out the answer. Here's the question...
Both cells are drawn the same length, but the magnification of each cell is different. The real length of the bacterial cell is 2 micrometers(The magnification x 50 000). Calculate the real length , X, of the plant cell(The magnification x 500). Give your answer in micrometers.

Magnification= image size divided by real size so

First you need to work out the image size so:
Magnification x real size
50 000 x 2 = 100 000

IMAGE SIZE FOR BOTH= 100 000

Plant cell = image size divided by magnification
100 000/500 = 200

200 is my final answer. I hope this helped, try to remember the formula x
