Width of the rectangle is 12m
<u>Explanation:</u>
<u></u>
Area of rectangle = 44m
height = ![\frac{11}{3}m](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B3%7Dm)
area of rectangle = length X breadth
![44 = \frac{11}{3} X b\\b = 12m](https://tex.z-dn.net/?f=44%20%3D%20%5Cfrac%7B11%7D%7B3%7D%20X%20b%5C%5Cb%20%3D%2012m)
Therefore, width of the rectangle is 12m
You would need more details like the y values or something. Rate of change is slope though if that helps you enough to figure it out
