The scale of the drawing is 1:4, this means that each centimeter of the drawing corresponds to 4 meters in real life.
To determine how long is the volleyball court in real life, given that its length on the drawing is 4cm you have to use cross multiplication:
1cm → 4m
4cm → xm
Both relationships are at the same ratio so that:
[tex]\begin{gathered} \frac{4}{1}=\frac{x}{4} \\ 4=\frac{x}{4} \\ 4\cdot4=4\cdot\frac{x}{4} \\ 16=x \end{gathered}[/tex]The length of the volleyball court is 16 meters.
