Answer 1

Answer: The actual pool is 44 m long.

Explanation:

Given : The scale used for drawing :

9 mm: 4 m

i.e. for each 1 mm of drawing we have
`(4)/(9)\ \text{m}` of actual pool.

If the pool is 909 m long , then the actual pool will be
`\frac49*99= 4*11=44\text{ m long.}`

hence, the actual pool is 44 m long.
