Answer:
234 ft²
Step-by-step explanation:
Since we can only find area of polygons with a regular shapes, lets cut the polygon into two regular rectangles, the top rectangle and the bottom rectangle.
Top Rectangle = 12 x 3 = 36 ft²
Bottom Rectangle = (12 + 3 + 3) x 11 = 198 ft²
Area of the polygon = 36 + 18 = 234 ft²
