Answer:

C 5/2

Step-by-step explanation:

we can observe that going from R to R' is an expansion (increase in size) and hence the scale factor must be greater than 1 (i.e the numerator must be larger than the denominator)

the scale factor is simply the ratio of any 2 corresponding sides.

Lets pick the short sides

Short side of R' / Short side of R

= 10/4

= 5/2
