Given:
The parallel sides of a trapezium are 28.7 cm and 22.3 cm.
The distance between parallel sides is 16 cm.
To find:
The area of a trapezium.
Solution:
The area of the trapezium is:
Where, 
are parallel sides and 
is the vertical distance between the parallel sides.
Putting 
in the above formula, we get
Therefore, the area of the trapezium is 408 square cm.
Answer:
34
Step-by-step explanation:
The correct answer is ( A )
let me know if you need explanation.
You first need to isolate the y
4x+9y=-108
9y=-4x-108 (subtract 4x from both sides)
y=-4/9x-12 (divide both sides by 9)
Then, by using the y=mx+b form, we can tell that the y-intercept is -12 so A
Hope this helps
