Answer: The area of the shaded region is 30 cm^2

Explanation:

First, we recall the area for a rectangle and a triangle.

-Area for rectangle: A = L x W

-Area for triangle: A = 1/2 x b*h

Next, I find the area of the total region.

-12 cm x 4 cm = 48 cm^2

Then, I find the area for the non-shaded region (or the white triangle)

- A= 1/2 x 9*4

- A= 1/2 x 36

- A = 18 cm^2

Finally, I subtract the total area of the whole region from the non-shaded region ( or again white triangle)

- 48 minus 18 = 30 cm ^2
