1. Double Integrals

I have two questions that I've been having problems with, mainly finding the bounds of x and y, if anyone could help me with that part of the problem it would be greatly appreciated, thanks

for this one, since it's an average value, do the bounds have to be numbers and not functions for both x and y?

for the first one

$\int^{\frac{1}{4}}_{0}\int^{\sqrt{x}}_{2x} ye^x dydx$

3. The formula is

$\frac{1}{area} \int\int f(x,y) dydx$

i got the second one but am still struggling with this one, can anyone help me out with the actual integration?
