Answer:
3 (i think) ,
Coordinate W' = (-1.5, 0.5)
Coordinate X' = (0.5, 0.5)
Coordinate Y' = (0.5, -0.5)
Coordinate Z' = (-1.5, -0.5)
Step-by-step explanation:
Not completely sure this is right as I haven't done this in a while, but since the scale factor is 1/2 you'll be halving all the coordinates values and then find the new perimeter that way.
