Answer:
[tex]\frac{1cm}{4 meters}[/tex]
Step-by-step explanation:
To find the scale, we write a ratio of [tex]\frac{map}{real world}[/tex] and simplify.
Assuming the 40 meter side corresponds to 10 cm, we know [tex]\frac{map}{real world}=\frac{10cm}{40 meters}[/tex]. We simplify to [tex]\frac{1cm}{4 meters}[/tex]
