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


Answer:
d and b and f
Step-by-step explanation:
Answer:
x = 20
y = 7.2
Step-by-step explanation:
12/x = 9/15
9x = 180
x = 20
12/x= y/12
12/20 = y/12
144 = 20y
y = 7.2
y = 20
Would it not be one hundred and[insert number]?
