Find the area of this trapezoid. Explain or show your strategy.

Lin and Andre used different methods to find the area of a regular hexagon with 6-inch sides. Lin decomposed the hexagon into six identical, equilateral triangles. Andre decomposed the hexagon into a rectangle and two triangles. Find the area of the hexagon using each person’s method. Show your reasoning.

On the grid, draw three different triangles with an area of 8 square units. Label the base and height of each triangle.
