#### Solution

From the given figures,

Length of volleyball court = 18 m

Breadth of volleyball court = 9 m

Length of pool = 75 m

Let the width of swimming pool = x m

Given, the size of volleyball court and swimming pool are in direct proportion to each other.

∴ `9/18 = x/75`

⇒ `x = (75 xx 9)/18 = 75/2` = 37.5 m .....[By corss-multiplication]

Hence, the width of the swimming pool is 37.5 m
