Answer:
w = ![l + \frac{25 - l^{2}}{l - 5}](https://tex.z-dn.net/?f=l%20%2B%20%5Cfrac%7B25%20-%20l%5E%7B2%7D%7D%7Bl%20-%205%7D)
(Anyone can correct me if I'm wrong)
Step-by-step explanation:
Before we start the solving, we can make the following statements:
Area = l x w
Area = 5x + 25
therefore,
l x w = 5x + 25
Since the question states that the length is x more than the width, so we can make the following statement:
w = l + x
With this, we can substitute it to the first statement we made, l x w = 5x + 25,
l x (l + x) = 5x + 25
+ lx = 5x + 25
lx - 5x = 25 - ![l^{2}](https://tex.z-dn.net/?f=l%5E%7B2%7D)
x(l - 5) = 25 - ![l^{2}](https://tex.z-dn.net/?f=l%5E%7B2%7D)
x = ![\frac{25 - l^{2}}{l - 5}](https://tex.z-dn.net/?f=%5Cfrac%7B25%20-%20l%5E%7B2%7D%7D%7Bl%20-%205%7D)
From this, we can find w by substituting it in the statement we made earlier, w = l + x,
w = ![l + \frac{25 - l^{2}}{l - 5}](https://tex.z-dn.net/?f=l%20%2B%20%5Cfrac%7B25%20-%20l%5E%7B2%7D%7D%7Bl%20-%205%7D)
