Question

The figures below are similar. Compare the smaller figure to the larger. Which of the following is the ratio of the perimeters of the figures?

Answer 1

Answer: first option

Step-by-step explanation:

As you can see in the figures shown in the image attached, the lenght of a side of the smaller figure is 2 inches and the the lenght of a side of the larger figure is 4 inches.

Therefore, you can find the ratio as following:

$ratio=\frac{2in}{4in}$

Now, you must reduce the fraction. Therefore, you obtained that the ratio of the perimeters of the figures is:

 $ratio=\frac{1}{2}$

Which can be written in the following form:

$ratio=1:2$

Then, the answer is the first option.
