Because the quadrilaterals are similar, the ratio of the longest side of the first quadrilateral to the longest side of the second quadrilateral is the scale factor.
20/5 = 4/1 or 4:1 is the scale factor.

You have three equations to solve:

1)  20/5 = 18/z
Cross multiply and solve for z.

2)   20/5 = 16/y

3)    20/5 = 12/x
