Currently, in 2.2.1 and later, hatching area is calculated by analytical algorithms, meaning precision to 10^-8 or better.

Yes, it's currently required to create a hatch to use the area calculation (aside from the polygon area method), the hatching method is designed to support areas with edge curves of the types: lines, circle, ellipses, parabolas etc.

More work is needed to get this feature user friendly.

Thank you very much. That is certainly useful!
By the way I am quite perplexed that it is not easier to calculate areas on LibreCAD. Being able to quantify the spaces that you are drawing is an essential part of architectural and urban planning work.
