Answer:
Step-by-step explanation:
alright, lets get started.
The area of the rectangle is given by the formula : [tex]length*width[/tex]
Suppose the length of the pool is l
area is given as 90 and width is given as 9
Plugging the values in formula:
[tex]90=9*l[/tex]
Dividing 9 in both sides
[tex]l=\frac{90}{9}=10[/tex]
So, the length of the pool is 10 meters. : answer
