Given the dimensions od rectangle A:

9 in by 3 in

Since rectangle B is a scaled copy of rectangle A, this means that rectangle B and rectangle A has the same scale factor, they have the same shape but maybe different dimensions.

The scale factor of rectangle A:


(9)/(3)=\text{ 3}

Now, let's check the answer choices for a similar scale factor of 3:

A. 4.5 by 1.5:


(4.5)/(1.5)\text{ = 3}

B. 8 inches by 2 inches:


(8)/(2)\text{ = 4}

C.10 Inches by 4 inches:


(10)/(4)\text{ = 2.5}

D. 13.5 inches by 4.5 inches:


(13.5)/(4.5)\text{ = }3

E. 90 inches by 30 inches:


(90)/(30)=3

We can see that options A, D and E are correct

ANSWER:

A. 4.5 by 1.5 Inches

D. 13.5 inches by 4.5 inches

E. 90 inches by 30 inches
