Answer: The name of a polygon with 40 sides is tetracontagon or tessaracontagon.
The name of the polygon with 40 sides is 40 –gon.
Solution:
Given that, we have to find the name of a polygon with 40 sides from the given four set of options .
Now, let us check the options once,
Quadecgon ⇒ quad – deca – gon ⇒ 4 x 10 – gon ⇒ 40 sides
Pentaoctagon ⇒ penta – octa – gon ⇒ 5 x 8 – gon ⇒ 40 sides
40 – gon ⇒ 40 sides
Hetagon ⇒ hepta – gon ⇒ 7 sides
Here last option is irrelevant , so let us eliminate it.
Now, options 1 and 2 are having more than 1 numerical prefixes which is unusual.
Hence, the name of the polygon with 40 sides is 40 – gon.
