Answer:
A, D, and E
Step-by-step explanation:
The ratio between the sides of the rectangle is 12/3 = 4. In a scaled copy of rectangle A, the ratio between the sides needs to be 4 too.
For answer A the 6/1.5 = 4, has the same ratio therefore is a scaled version of rectangle A
For answer B the 10/2 = 5, it does not has the same ratio therefore is not a scaled version of rectangle A
For answer C the 13/4 = 3.25, it does not has the same ratio therefore is not a scaled version of rectangle A
For answer D the 18/4.5 = 4, has the same ratio therefore is a scaled version of rectangle A
For answer E the 80/20 = 4, has the same ratio therefore is a scaled version of rectangle A
