Here is a polygon. All measurements are in centimeters.

A heart-shaped polygon. Arrows along the bottom indicate the width of each half of the polygon is 6. Arrows along the top indicate that each of the six sides at the top span 2 units. Arrows along the right side indicate that the top portion of the polygon is 2 units, the middle portion is 3 units, and the bottom portion is 6 units.

1. Decompose this polygon so that its area can be calculated.
2. Calculate its area. Organize your work so that it can be followed by others.
