The formal name is hectaicosikaihenagon. Most people, including mathematicians, will use 121-gon since that effectively communicates the size of the polygon. But, if you want to appear pretentious or be obfuscatory, by all means use the Greek prefices.
A 121-sided shape is a polygon if it is a plane figure and a polyhedron if it is a solid (3-dimensional) figure.
