Some time ago I tried to establish the areas/perimeters for nine versions
of Dublin City from 1780 to 1985.Have recently found some results but am
unsure if they are acres/hectares/sq kms and for the perimeters. etc.
I list them below and would ask if one of you could please solve this for
me and remind me how to do it in JOSM or QGIS. I am still at the early
stages of QGIS 3.14.
