Answer:

180

Step-by-step explanation:

1- you can take the rectangular part of the shape because it is easy to calculate: length×width which is 9×15= 135

2- Now you take the triangular part of the shape which you can calculate by width×length× 1/2. The width is 15-9= 6 so 6×15×1/2= 45

3- Add them together to get the full area 45+135= 180
