Something like this perhaps,
BW=bwareafilt(~yourBinarizedImage,3);
regions=regionprops(BW,'Image');

In particular, regionprops and ask for 'Area'

Depending on what "matrix of the area" means... To me, it sounds like the sub-image containing the bounding box of the regions.

I would interpret it as a single matrix containing all three areas.
Areas = [regions.Area];
