Two areas of similar figures relates by the scale factor
.
- If length of one figure is A, and corresponding length of another figure is B, then they are related by:

- If area of one figure is A, and corresponding Area of another figure is B, then they are related by:

So we can write:

Since, perimeter is also length, the ratio would be

Similarly, ratio of their areas should be

Answer choice A is right.
