In this video, we calculate the area of the watershed that we delineated by examining the flow accumulation value at the outlet and multiplying it by the raster pixel size (in projected linear units) and, alternatively, convert the watershed raster to a polygon and create a new field in its attribute table and calculate the area using the 'calculate field' geoprocessing tool. We see that both method return (approximately) the same area.
