Display area and center of area in Sketch?

Hi all,

I'm designing a ship, and now I have to sketch some polygons while keeping an eye out for resulting area and center of area. Much like COG/COM of Solid.

I figured out that I can extrude the polygon, and then add Reference Geometry->Center of Mass, but this is counter-productive, since I'm now in Sketch (2d) stage, I don't want to go to 3d just for reference.

As for the area of polygon itself, I have no idea.

I'm not attaching any design, just imagine the situation: I open new Part, Sketch 5 corner enclosed polygon, and I now want to move it (and dimension), and while doing that, SolidWorks would dynamically show the resulting area of that polygon and center of that area. Much like driven dimensions.

How do I do this?
