Simple Q: How to give computed results from NSolve to a new

Hi, guys,

I am new to Mathematica. And I just have a simple question for you:

I have solved a system of equations by NSolve. And for instance, it returns the results as 
Root={{x->1,y->2}}.

And now I want to use the computed results, say x & y to define a new variable 
Z=x^2+sqrt(xy).

How should I use computed x and y to define the new variable Z?

Thanks in advance.
