not really sure how to go about this. tried to set up a double integral and use polar coordinates but dont know what boundaries to use etc.

fy = 2y; fz=2z

A(S)=int int sqrt{1+4y^2 +4z^2}dA

then I switched to polar coordinates i tired to integrate from theta=0 to pi/2 and r= 0 to a

but didn't get anywhere with this.
