<em>Because OP only asked for a clarification of the problem statement: </em>
You are asked to find the green area. (Hint: divide the green area into rectangles and right triangles, because you know their area.)
So the first thing that happens here is that the triangle is rotated 90 degrees clockwise. This can be seen because it is rotated, then you also notice that the triangle is reflected across the y axis.
(2-3)/(-1-4)
-1/-5
the answer is A
hope this helps!
