Step 1: Label the given image accordingly. Step 2 Calculate the area of the hexagon denoted as A1. First, find its apothem using special right triangle (30°-60°-90°) and the Pythagorean theorem. Next, use the area formula for regular polygons to calculate the area of the hexagon. Alternative Way. Use hexagon area formula that uses side length s. Step 3: Calculate the area of the square denoted as A2. Step 4: Calculate the area of the triangle denoted as A3. Notice that the hexagon's apothem is also the triangle's height. Step 5: Finally, calculate the area of the shaded region denoted as A using addition and subtraction.
