Show us what you have done so far.

Tell us what Green's theorem is, and how that applies to the
function you are given.

The region you are integrating over is not the interior of the
triangle.

You define the region by:

$-2\ <\ x\ <\ 2$ and $0\ <\ y\ <\ 2$,

which is a rectangle. I think (and you will have to check this) that what
you need is:

$-2\ <\ x\ <\ 2$ and $y\ <\ -|x|+2$.
