See my Image Segmentation Tutorial : http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 This well-commented tutorial goes over all that in excruciating detail explaining each step of the way. It also does some size filtering and cropping after segmentation, in case you're interested in that.

You can calculate the area of a segmented image using the regionprops function:

area = regionprops(your_image_name , 'Area')
