POLYGON ANGLES
For any polygon of n sides:
Use the fact that the perimeters of the hexagon and triangle are the same in order to figure out the
length of each side of the triangle.
Use the formula for the area of an equilateral triangle to get to your answer.
The answer is (B).
Sum of Interior Angles = (n − 2) × 180°
Sum of Exterior Angles = 360°
