Okay, so I am working on a model that is mostly just a series of tools. However I have dissolved 2 data layers within the model and I wish to calculate the acreage of the 2 new layers which each consist of only 1 feature each. I have added the Add Field tool for both of my outputs and now need to calculate the field value within the model using the calculate field tool. The problem is that I am a complete beginner in python and have no idea how to go about scripting this. It doesn't seem like this should be too much of an issue, but nothing I have found so far in the forum has helped me out. Anybody have any ideas? I still have to figure out how to calculate the percentage of overlap between the 2 layers after I get within my model as well.

Any help would be appreciated.

An example in your case:

Side note - you can do a "Calculate Geometry" within the app, see the following:
