Dear experts! I have an projekt there area is let say 100 000m2 in 25 polygones, I want to select 5 polygones wich have a specifik attributes. Lets say this 5 polygones have an area about 3 000m2. Now I want let the program count how many procent this 3 000m2 is about the total 100 000m2. I try to select a SQL question but didn´t found out how to do, or must I use something else for select out this area in procent? I use ArcGIS10. Thanks for helps!
