EASY MATH PLEASE HELP!! I WILL GIVE BRAINLIEST!

QUESTION: Find the area of the shaded part. (ROUND YOUR ANSWER TO THE NEAREST WHOLE NUMBER)
(DONT FIND THE AREA OF THE TRIANGLE FIND THE AREA OF THE GREY SHADED BOX NOT INCLUDING THE TRIANGLE)

I’m not positive but i think it’s none of your buisness

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
