For a certain rectangular region, the ratio of its length to its width is 35 to 10. If the width of the rectangular region increases by 7 units, how must the length change to maintain this ratio?
Correct answer: B. It must decrease by 24.5 units.
- A. It must increase by 24.5 units.
- B. It must decrease by 24.5 units.
- C. It must decrease by 7 units.
- D. It must increase by 7 units.
Explanation
The correct answer is Option B. The length must decrease by 24.5 units when the width of the rectangular region increases by 7 units to maintain the ratio of 35 to 10. This can be calculated by setting up a proportion and solving for the change in length. The other options are incorrect because they do not account for the necessary change in length to maintain the given ratio.
