In addition, histograms tend to be rectangles while a frequency polygon resembles a line graph. First, open up an ArcGIS session and load in the polygon data you want to calculate the area on. Since srs 1 and r 1 agree at Aand at B, they agree on the polygon, so srs 1 = r 1. How to Calculate the Area of Polygon in ArcMap.
