Make changes to CAD file and share output

Job ID: 32298582

Budget: €30 – €250 EUR

I have 3 similar simple floor plans (80m2, 70m2 and 50m2 areas) for Existing and New situation in pdf (done with manual adjustments in pdf, not in CAD). Only thing incorrect in the pdf file is the areas in m2.
I also have the original CAD (.dwg) file for the floorplans before all the adjustments.
The ask is to:
1) include the adjustments that are now visible in the pdf file into the original CAD file (it has to be identical except the m2),
2) calculate the areas right (m2), and
3) share back the updated .dwg file, 1 pdf output for the 3 existing floorplans, and 1 pdf output for the 3 new floorplans (they would be almost identical to the ones I already have, but with the correct areas in m2).

I attach a sample of the New floorplans in pdf as example. Upon task assignment I will share the 2 pdf complete files and the *.dwg file
