A volleyball court is in a rectangular shape and its dimensions are directly proportional to the dimensions of the swimming pool given below. Find the width of the pool.
उत्तर
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
