Answer:
To find the scale factor, you need to divide the width of the large figure by the width of the smaller figure (4/1). You also need to divide the length of the large figure by the length of the smaller figure (8/2). After you divide these numbers, you'll get 4 as an answer. Therefore, the scale factor from the small to larger figure is 4.
4/1 = 4
8/2 = 4
