Sorry, no. Draw doesn't do any sort of calculations; it's purely a graphics tool.
That said, it is possible to extract the coordinates from Draw, copy them to a spreadsheet, and do whatever calculation you want. See this thread for an example, and a link to the extension that allows it: viewtopic.php?f=11&t=21044
I expect it wouldn't be all that difficult to write a macro program to do the calculation in Draw, but I would wonder if you'll get good results. Wouldn't you need some real GIS software to do it well?
