First, we can see that there are four sides, and none of these equation contradict each other, so it is safe to say that <em>this is a quadrilateral</em>.
Second, all of the equations have the slope of <em>0 or undefined</em>, so it is a rectangle.
Lastly, the four points of intersection shows us that the side lengths are <em>3 and 5</em> units, so the area of it is 15 units².
This problem is not easy but use division and multiplication
Then they all will equal the same thing when you divide them.
Example: A = 5 B = 20 20 divided by 5 = 4
C = 28 D = 7 28 divided by 7 = 4
