Use the image to answer the question.
A polygon shows an outline in the shape of a house with a triangular roof, a door and a chimney, standing on two base pillars. The length of the two rectangular pillars is 4 and the width is 3. The gap between the two pillars, or the door, measures 2 across and the inner side of the vertical pillars measures 3.5. The perpendicular height of the triangular roof is 6. The sides of the triangle base extending outward from the outer side of both pillars is 2. The sides of the chimney sitting on the slanted roof on the right measure 1 and 2 and its thickness is 1.
Find the area of the polygon. Assume that segments that appear congruent are congruent and angles that appear to be right angles are right angles.

The area of the polygon can be calculated by finding the areas of the individual shapes that make up the house and then adding them together.
Area of the roof (triangle): 1/2 * base * height
Area of the roof = 1/2 * 5 * 6 = 15 square units
Area of the base (rectangle): length * width
Area of the base = 4 * 3 = 12 square units
Area of the gap (rectangle): length * width
Area of the gap = 2 * 2 = 4 square units
Area of the chimney (rectangle): length * width
Area of the chimney = 1 * 2 = 2 square units
Total area = 15 + 12 + 4 + 2 = 33 + 17.5 = 50.5 square units
Therefore, the area of the polygon is 50.5 square units.
