Question 1105934
<br>
1. Corresponding sides KL, length 15, and QR, length 12, set the scale factor as 4:5, or 4/5, between PQRS and JKLM -- not between JKLM and PQRS.<br>
2. Side QP, length w, corresponds to KJ, length 25.  Is 20/25 equal to 4/5?<br>
3. Side LM, length x, corresponds to RS, length 10.  Is 10/12 = 4/5?<br>
4. Side JM, length y, corresponds to PS, length 16.  Is 16/20 = 4/5?<br>
6. From part 2, we know that the perimeter of PQRS is 58.<br>
5. From part 6, is 58/72 = 4/5?<br>
7. The ratio of the perimeters is 4/5... but is it PQRS to JKLM, or JKLM to PQRS?
