A 41-sided shape is called a tetracontakaihenagon in mathematics. The naming convention for polygons uses Greek numerical prefixes, with "tetraconta" representing 40 and "henagon" representing a 1-sided polygon (which is a circle). Therefore, a 41-sided polygon is a tetracontakaihenagon.

Oh, dude, a 41-sided shape is called a tetracontakaihenagon. Yeah, I know, it sounds like a made-up word, but apparently, that's the legit term for it in math land. So, if you ever need to impress someone at a party with your knowledge of obscure shapes, there you go.
It's a 41 sided polygon.
a line can be described as 2 sided with interior angles totalling 0 degrees a triangle is 3 sided and has interior angles totalling 180 degrees a rectangle is 4 sided and has interior angles totalling 360 degrees ... you should be able to finish the homework problem from that...
the sum of angles of a polygon is 180 x (n-2) whefe n is the number of sides re equating your question 7020 = 180 x (n - 2) = 180n -360 rearranging this gives 7380 = 180n therefore n is 7380 divided by 180 = 41 therefore a 41 sided polygon !!
C = 90 - 41 = 49 deg S = 180 - 41 = 139 deg
