Area of Composite Shapes and Shaded Regions

Imagine Aria, Rohan, and Anika are on a treasure hunt. They stumble upon an ancient map with a figure drawn on it. The map holds the key to the next clue, but to proceed, they need to calculate the area of the figure. Can you help them figure it out?

Answer explanation

The correct answer is 275 cm^2 because the figure is a rectangle with dimensions 25 cm by 11 cm, so the area is 25 * 11 = 275 cm^2.
