Find the area of the irregular figure. Use 3.14 for .
A = bh
A = 16 • 9A = 144
Step 1: Separate the figure into smaller, familiar figures.

A ≈ 100.48
Area of the parallelogram:
Area of the semicircle:
A ≈ 144 + 100.48 = 244.48
The area of the figure is about 244.48 m2.
Step 3: Add the area to find the total area.
