If you can threshold the yellow area and that represents all your cells, then you can do an AnalyzeParticles and evaluate individual particles to determine the variation in size of the individual cells (those that happen to be separate from clumps of cells). You can write a method to find the most common size bin for your particles, and that will be your individual cell area range.  Divide the total yellow area, i.e., all cells, individual and clumped, by the mean of the individual cells and you get the estimated number of cells and error bars of the individual cell size variation.  This form of cheating is called “statistics” ;-)
