how to calculate area of objects in an image in matlab??

threshold the image, bwlabel it, then use regionprops() or else use

sum(LabeledImage(:) == ObjectLabel)

Try this:

props = regionprops(binaryImage, 'Area');
allAreas = [props.Area]

With regionprops():

labeledImage = bwlabel(binaryImage);
measurements = regionprops(labeledImage, 'Area');
allAreas = [measurements.Area]
