I believe it’s the 3rd one Bc you can see how it has both positive and negatives numbers (it’s all over the place) while the other ones remain positive or negative making it either a positive correlation or negative correlation. Make sense? Or am I just wrong completely. ♀️
On enlarging the rectangle, the proportion or ratio of Length to Height will stay the same.
The ratio of original length to height is 13 : 6
The ratio in enlarged rectangle will stay the same. Let the height of enlarged rectangle is y cm. So we can write:
![13:6=19.5:x \\ \\ \frac{13}{6} = \frac{19.5}{x} \\ \\ x=19.5* \frac{6}{13}=9](https://tex.z-dn.net/?f=13%3A6%3D19.5%3Ax%20%5C%5C%20%20%5C%5C%20%0A%20%5Cfrac%7B13%7D%7B6%7D%20%3D%20%5Cfrac%7B19.5%7D%7Bx%7D%20%5C%5C%20%20%5C%5C%20%0Ax%3D19.5%2A%20%5Cfrac%7B6%7D%7B13%7D%3D9%20%20)
Therefore, the height in enlarged rectangle will be 9 cm
