Math Problem Statement
Solution
To find the area of this irregular polygon, we can break the shape into smaller, simpler shapes (rectangles, triangles) and calculate the area of each one individually, then sum them.
Looking at the figure, it can be divided into:
-
A large rectangle on the left:
- Dimensions: 9 ft by 14 ft
- Area =
-
A smaller rectangle on the right top:
- Dimensions: 3 ft by 6 ft
- Area =
-
A right triangle on the bottom right:
- Base: 9 ft (horizontal length)
- Height: 6 ft (vertical length)
- Area =
Total Area:
Now, sum the areas of the three parts:
Thus, the total area of the figure is 171 square feet.
