Develop a Graphical User Interface (GUI) that allow the user to select a geometric
shape for a lamina or plate and then display its properties. The properties include:
Area, Perimeter, Center of mass, Moment of area, Mass, and Moment of Inertia.
The user can select a material where the program will determine the density and use
it to compute the mass. The user can select: square, triangle, rectangle, and define
the thickness. The program will display the shape and the location of the center of
