Calculating percentage of areas in Model Builder

Discussion created by annisaindah on Jun 7, 2011
Dear All,

I have shp file which contains attributes "Water body" and "Areas".
"Areas" is the total area in each water body. I have done this in Model Builder ArcGIS 10.
Now, I want to calculate the percentage of area in each water body (areas/sum of areas*100).
I can do this manually in attributes table. So, is there any chance to do it automatically in Model Builder?

In Summary Statistics, i found the way to sum the area. Okay this is fine... but then when I add field "percentage", how can i connect the result of sum the area to my calculation?

Many thanks before for the hint!
