I am trying to put together an activity for school groups to introduce them to ArcGIS online in an interactive and meaningful way without the need for people to go outside to take points/lines/polygons. Our activity is being built around arcmaps online, and we are getting them to draw polygons over specific habitat types (woodland, savanna, prairie etc.). For each of those new polygons we need to know the area, and I cannot figure out a simple way to get the area of a newly drawn polygon (created using "add map notes"). I know that there is the measurement tool, but that means they have to draw essentially two polygons for each new polygons. I feel like there has to be an easier and more straightforward way to get the area out of these new shapes. Any ideas?
