Answer:
D. 137 ![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
Step-by-step explanation:
First, get the area of the rectangle:
![A_{Rectangle} =length *width](https://tex.z-dn.net/?f=A_%7BRectangle%7D%20%3Dlength%20%2Awidth)
![A_{Rectangle}=(15)(11)=165](https://tex.z-dn.net/?f=A_%7BRectangle%7D%3D%2815%29%2811%29%3D165)
Then, get the area of the triangle:
![A_{Triangle} =\frac{height*base}{2}](https://tex.z-dn.net/?f=A_%7BTriangle%7D%20%3D%5Cfrac%7Bheight%2Abase%7D%7B2%7D)
![A_{Triangle}=\frac{8*7}{2} =28](https://tex.z-dn.net/?f=A_%7BTriangle%7D%3D%5Cfrac%7B8%2A7%7D%7B2%7D%20%20%3D28)
Now substract the area of the triangle from the rectangle:
165 - 28 = 137
∴ 137 ![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
