B. 4A.

We know, XL + (Y-X)(L-M) = A

New Area is 2X*2L + (2Y-2X)(2L-2M)
=>4XL + 4 (Y-X)(L-M)
=>4A.

B is the answer.

Paul, how did you solve using the graph ? I am trying to find out easy way to do problems for which I took a long time.

The portion in red is original the figure. The yellow portion is when every side is multiplied by 2. You can clearly see the 4A if red portion is A.

I saw this as a plug in, pure and simple (and I don't like plugging in too often - only where it makes perfect sense - here it did).

Since there's clearly an answer, and we're doubling every amount, and it's all proportional, then I just put down possible values for every side, got the area, and did it again with those values doubled.

Answer came out 4 times the original answer did.

Paul, I dug your method, too.

If you think about the shape as a rectangle (with a missing segment), then doubling each side results in a rectangle 4 times the size (with a missing segment of 4 times the size as well)... Hence 4A.
