Answer:

Step-by-step explanation:
we know that
The area of the figure is equal to the area of a triangle plus the area of a parallelogram
<em>Find the area of triangle KLM</em>

we have
--> difference of the x-coordinates points M and K
--> difference of the y-coordinates points L and K
substitute

<em>Find the area of parallelogram JKMN</em>

--> difference of the x-coordinates points N and J
--> difference of the y-coordinates points K and J
substitute

The area of the figure is equal to
