If you mean a polygon then it can have 3 or more sides
If you mean a polygon, as opposed to a poygon, the answer is a hexagon.

assuming you mean polygon. a polygon with 9 sides is a nonagon
4.9 cm times the number of sides in the polygon. Simple!
A polygon in the form of a trapezoid would fit the given description providing that it is not an isosceles trapezoid.
Such a polygon is called a regular polygon.
It is an irregular pentagon - a bit like a child's silhouette of a house with a pitched roof.
A polygon is described as "regular" if all its sides have the same length. (It will also turn out that all of its angles are equal.)
No, they are not.
The sum of the exterior angles of any polygon is always 360 degrees. To find the number of sides of a regular polygon with an exterior angle of 36 degrees, you can divide 360 by 36. This calculation shows that the polygon has 10 sides, making it a decagon.
