Answer:
(d) 2 11/12
Step-by-step explanation:

Split them into triangles and rectangles.
15 x 9 = 135
(6 x 3) / 2 = 9
135 - 9 = 126
This gives you the area of the rectangle with the triangle taken out of it.
15 - 6 = 9
(9 x 6) / 2 = 27
This gives you the area of the triangle at the top.
Add these together: 27 + 126 = 153, and that's your answer!
