Answer:

Measure of E'F' = 9

Explanation:

If a quadrilateral is dilated by a scale factor of
(3)/(4), all the sides of preimage CDEF will be dilated with the same factor to form image quadrilateral C'D'E'F'.

Scale factor =
\frac{\text{Dimension of image}}{\text{Dimension of preimage}}


(3)/(4)=(E'F')/(EF)


(3)/(4)=(E'F')/(12)

E'F' =
(3)/(4)* 12

= 9

Therefore, measure of side E'F' will be 9.
