if the scale in the drawing is 1 centimeter= 20 meters, then:

a) Playground 3 centimeters.


\begin{gathered} (1cm)/(20m)=\text{ }(3cm)/(x)= \\ \text{ x\lparen1cm\rparen=\lparen20m\rparen\lparen3cm\rparen} \\ x=\text{ 60 meters} \end{gathered}

b) Tennis courts= 5.2cm


\begin{gathered} (1cm)/(20m)=\text{ }(5.2cm)/(x) \\ x(1cm)=\text{ \lparen5.2cm\rparen\lparen20m\rparen} \\ x=\text{ 104 meters} \end{gathered}

c) Walking trail= 21.7 cm


\begin{gathered} (1cm)/(20m)=(21.7cm)/(x) \\ \\ x(1cm)=(21.7cm)(20m) \\ x=\text{ 434 meters} \end{gathered}
