Two figures are similar, and the scale factor is 2/3

d1i1m1o1n [39]

Answer:

The answer is 8.

Step-by-step explanation:

The scale factor between the figures is 2/3, this means that the ratio of the smaller figure to the larger figure is 2/3:

$\frac{smaller\:figure}{larger\:figure}=\frac{2}{3}$ .

So when a side of the the larger figure is 12 then:

$\frac{smaller\:figure\: side}{12}=\frac{2}{3}$

Therefore

$smaller\:figure\:side=\frac{2}{3}*12=8$ .

Thus the length of the corresponding smaller side is 8.
