area
That's the area.
the area is that 2 dimensional space inside of the closed figure. normally specified as square centimeters or square inches
There is no "space" inside a solid figure (body).However the solid figure can be measured in terms of its volume (the amount of space it occupies).
no gauss low is only applicable for closed paths. a plane sheet is not a closed path. for applying gauss law the charge must be inside the closed loop or path... ========================== I'll say "yes". Gauss' law says that the electric flux through a closed surface is proportional to the amount of charge inside the closed surface. The shape of the surface doesn't matter, and the shape of the charge distribution inside it doesn't matter either. If a closed surface encloses a part of a sheet of charge, then the flux through the surface is proportional to the amount of charge that's on the part of the sheet inside the surface. That doesn't bother me at all.

I do not know but: A closed figure is a figure with sides all around. (if the sides were fences and you were on the inside you could not get out witout climbing a fence)
Gauss's Law states that the total electric flux through a closed surface is equal to the charge enclosed by that surface divided by the permittivity of free space. In simpler terms, it describes how the total electric field passing through a closed surface is related to the total charge inside that surface.
A polygon is a closed plane figure bounded by straight sides. Since it is a closed surface, it has an interior (inside) and an exterior (outside). The interior angle of a polygon is the angle formed by two adjacent sides such that the angle is facing the interior of the polygon.
Yes
No, according to Gauss's law for magnetism, the total magnetic flux through a closed surface is zero. This is because magnetic monopoles do not exist, so the magnetic field lines always form closed loops.
It depends on the type of figure. If it is a 2D figure, then it is called area. If it is a 3D figure, then it is called volume.
surface area is the like the area of the outside of a 3 dimensional figure, area is the measure of what is inside a 2 dimensional
