Answer:
Wait what are we trying to solve here?
Step-by-step explanation:
S is 3 parts of R, or 9. 9 is 3/4 of 12, so R is 12. 12 plus 9 is 21, which is half of the full area of the rectangle. The area of the rectangle is 42 square centimeters. Now, we need to find what R is to the whole rectangle. We know that R is 12 square centimeters, and that the rectangle is 42 square centimeters. That ratio is 12 to 42. If it is simplified, that would be 6 to 21. If it is simplified further, you find that it is 2 to 7. Hope this wasn't too confusing, and I hope that I helped :)
