You didn't say what you're trying to find with your integral. Is it the area of the region Delta? That will determine what the integrand looks like.

You wrote this as your integral:

This is pretty much gibberish. I get that you're using 'S' to indicate an integral, but most of the rest makes no sense to me. What is "S sqrt(2)/2" supposed to mean? Are you integrating the constant sqrt(2)/2? With respect to what variable? Where did this constant come from?S sqrt(2)/2 -> 2 ( S x -> 2x dy) dx

What does "->" represent? I don't see how "S sqrt(2)/2" could be equal to what you have on the other side.

I don't think it's quite right. y=x is not always the lower bound on y (sometimes 1/x is) and y=2x is not always the upper bound on y (sometimes y=4/x is). I think you might have to break this up into a few integrals to get all of the different regions.
