I'm so stuck with theproblem right now T_TParametric Surface Area

Can anyone please help me out?

There are two questions in total, if you can help me with any one of the two, it'll be so appreciated!

Question 1:

The part of the plane 3x+2y+z = 6 that lies in the 1st octant.

Question 2:

The surface z = 2/3 (x^(3/2) + y^(3/2)), 0 <= x <= 1, 0 <= y <= 1

Please, help!
