A regular polygon is any 2-D shape where all the sides and angles are congruent.
Regular Hexagon
As denoted by the prefix "hexa-", hexagons have 6 sides and internal angles. The perimeter is equal to all 6 sides added together. However, we know that these sides must be congruent because it is a regular hexagon.
Solving for Perimeter
We can create an equation that describes the perimeter of this shape, with "x" representing the length of one side.
Since all the sides are equal we can use multiplication instead of addition. To solve this equation, divide both sides by 6.
This means that all sides must be 12 inches.
