I am given an image to load onto matlab. I have to determine the size of each face in the image in terms of pixels (i.e 48x48 pixels). Without using any matlab toolboxs, how could I find the size of the face?

Maybe try drawpolygon to trace the face. Then get the x,y coordinates of what you drew and call polyarea.
