The term that refers to the total length around a polygon is perimeter. Perimeter is calculated by adding together the lengths of all the sides of the polygon. This measure gives you the complete distance around the shape, which is a fundamental concept in geometry.

Area refers to the amount of space contained within a shape, measured in square units, while volume relates to the amount of space a three-dimensional object occupies, measured in cubic units. Diameter is a term specific to circles, referring to the distance across the circle through its center, and does not apply to polygons. Therefore, perimeter is the appropriate term for the total distance surrounding a polygon.
