8-76.
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 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?

$\frac{3}{4}$

Use the ratio of similarity to find the perimeter.

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