Find the area of the shape shown below.

28 square units.

Step-by-step explanation:

Let us divide the shape into two rectangles and a right triangle. The resulting composite figure is attached.

As we see in the figure the area of the triangle is

.

The area of the bigger rectangle is (it's actually a square )

,

and the area of the smaller rectangle is

.

Therefore, the total area of the shape is

both equations and proportions are better.
