8-70.
1. Assume Figure A and Figure B, at right, are similar. Homework Help ✎

1. If the ratio of similarity is , then what is the ratio of the perimeters of Figures A and B?

2. If the perimeter of Figure A is p and the linear scale factor is r, what is the perimeter of Figure B?

3. If the area of Figure A is a and the linear scale factor is r, what is the area of Figure B?

$\frac{3}{4}$

If the perimeter of Figure A was 5 and the scale factor was 3, how would you find the perimeter of Figure B?

If the linear scale factor is r, what is the area ratio?
