I am using ArcMap 10.2.2 and can't get the measure tool to measure an area. For some reason The option to measure an area is not available for selection. Any ideas of how to activate it so I can measure an area of a polygon shape file?
The data frame was using a geographic coordinate system which does not allow you to measure an area. I changed the data frame to a projected coordinate system which allowed me to activate the area measure tool.
