It is a convex polygon.
Only if you know what kind of polygon you have. If you know that you have a hexagon and one side is 1 cm, the perimeter is 6 cm. You only have to know the length of one side, since a regular polygon has equal sides. Perimeter or a regular polygon is the length of each side times the number of sides. You need to know both pieces to find the perimeter. ■
