How to find the objects' areas in this photo in mm^2?

[Rev. Cheeseman]

Hello, how to find the area in mm2 for both bone cross sections? Are there any online applications that allow us to instantly calculate areas? Thank you.

What are your thoughts on this? There are at least a couple ways that I know of to do this, but it would be better if you gave us your thoughts first. What accuracy is required for this?

Sorry, I don't understand because I only want to find the cross sectional areas for both bone cross sections. The right bone cross section seems to be bigger than the other but what about their cross sectional areas in mm2? Maybe the areas for both are the same?

Does each little square in the figure represent $1mm^2$?
