Answer:
36 square units
Explanation:
You want the area of the parallelogram with vertex coordinates (-6, 6), (-9, -3), (-5, -3), (-2, 6).
Area
The area of a parallelogram is the product of the base length and the height perpendicular to that base.
Here, the base is a horizontal line, so its length is the difference of the x-coordinates of the end points:
-5 -(-9) = 4 . . . . base
The height is the difference of y-coordinates between the top edge and the bottom edge:
6 -(-3) = 9 . . . . height
Then the area is ...
A = bh = 4·9 = 36 . . . . square units
