Define four spatial co-ordinates.
Please elaborate, is there any issue?
or
RGB=insertShape(I,'rectangle',[Position],'LineWidth',xx);

Are you looking for this one?
im=imread('test.jpg');
%[Xmin Ymin width length].
%Values are for example purpose only
Xmin=24;
Ymin=25;
length=20;
width=20;
%%
result=insertShape(im,'rectangle',[Xmin Ymin Xmin+length Ymin+width],'LineWidth',2);
imshow(result);
