Its area.
That's the area.
a closed, flat figure is a polygon. But it is only a polygon when it is not round.
Closed
Any closed figure formed by a set of straight linesegments is a polygon. If the segments are curved such as in a circle or oval, the closed figure is not a polygon.
area
Its area.
-- The amount of paper you'd have if you cut the figure out. -- The amount of carpet you need to completely cover the figure.
It is the area of its foot-print.
That's the area.
closed figure
yes, a triangle is a closed figure
A triangle has the fewest amount of sides possible to create a closed figure.
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.
Yes. A simple closed figure is counted as a polygon for a polygon is closed.

A pentagon. A closed figure means that all the lines of the figure are connected.
