Solve the following problem using what you know about composite figure. What is the area of the figure?

A. 24 square units
B. 48 square units
C. 30 square units
D. 36 square units

To find the area of the figure, we need to break it down into simpler shapes and then add up their areas.

The figure can be broken down into a square with side length 6 units and a right triangle with base 6 units and height 6 units.

The area of the square is (6 x 6) = 36 square units.
The area of the triangle is (1/2 x 6 x 6) = 18 square units.

Adding the areas of the square and triangle together, we get:
36 + 18 = 54 square units.

None of the provided answer choices match the calculated area of the figure, so there may have been an error in the calculations or the shape was not properly described.
