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
According to the question, the size of volleyball court and swimming pool are in direct proportion to each other.
∴ `9/18 = x/75`
⇒ `x = (75 xx 9)/18` ...[By cross-multiplication]
= `75/2`
= 37.5 m
Hence, the width of the swimming pool is 37.5 m
