Make a sketch, that's all, only then you'll be able to set up the double integral.

i understand, but the problem was that i was confused in how to set up the double integral. thankyou.

Do i need to seperate into two different integrals?

Yes:

where are just the equations of the lines making up the triangle. You can figure out which line is what right?
