I'm assuming "l" is actually supposed to be "large" and that you changed one of them after copying and pasting your code but forgot to change the other. Anyway, REGIONPROPS returns a struct array. You can't divide by a struct array but you could divide by the contents of the fields of that struct array. See the second of the Tips on that documentation page for how to create a vector from the struct.
