For my project, I want to calculate the geometry of individual polygons in my layer to find area and perimeter, however it is greyed out when I try to use this tool.
Beforehand, I set the data frame for map and display units to be in meters. I also did not put a projected coordinate system. However, I was able to find which polygons are within a certain distance (ex. 1000 m) from roads using the 'Select by Location' tool.
Why is it that ArcGIS can calculate distance but won't allow me to calculate the geometry of my individual polygons. Am I missing a step here?
