Answer: The actual pool is 44 m long.

Step-by-step explanation:

Given : The scale used for drawing :

9 mm: 4 m

i.e. for each 1 mm of drawing we have [tex]\dfrac{4}{9}\ \text{m}[/tex] of actual pool.

If the pool is 909 m long , then the actual pool will be [tex]\dfrac49\times99= 4\times11=44\text{ m long.}[/tex]

hence, the actual pool is 44 m long.
