There is insufficient information for us to answer this question. Please edit the question to include more context or relevant information. We have no idea what triangles uvw and xyz are! It would also be useful to develop the habit of checking your questions for completeness before posting them.
You increase the scale factor.
Tautologically!
The area scale factor is the square of the side length scale factor.
6x3y3z3(-4x2y2 + xyz + 3z)
x(vw + wy - yz)
Scale factor and perimeter are related because if the scale factor is 2, then the perimeter will be doubled. So whatever the scale factor is, that is how many times the perimeter will be enlarged.
