stats = regionprops(YOUR_BW_IMAGE, 'Area');
areas = [stats.area];
total_area = sum(areas);

areas = [stats.Area];
total_area = sum(areas);

It's a generic, general purpose demo of how to threshold an image to find blobs, and then measure things about the blobs, and extract certain blobs based on their areas or diameters.
