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?
