Answer:

y=3

Step-by-step explanation:

Assuming this is an enlargement where EFGH is enlarged to ABCD then the former is the object and the latter is the image. If so then

scale factor(k) of the enlargement=image length/corresponding object length

k=3/2

Therefore, y=4.5/k

y=4.5/(3/2)

y=3

If we take the assumption another way and say ABCD is reduced to EFGH then the former is the object and the latter is the image.

In that case,

k=⅔

y=4.5×k

y=3

In either case y=3units
