We have a scale that relates the measures in a model with the measure in the real world.
The scale is 1 cm = 0.5 m, meaning that 1 cm in the model represents 0.5 m in the real world.
If we want to know what real world measure is representd by 8 cm in the model, we can use the Rule of three as:
[tex]\begin{gathered} 1cm\longrightarrow0.5m \\ 8cm\longrightarrow x=8cm\cdot\frac{0.5m}{1cm}=4m \end{gathered}[/tex]We can see that 8 cm in the model represents 4 meters in the real world.
Answer: 4 meters.
