Forest map dimensions

On a 1:150000 scale map, what will be the dimensions of a strip of the forest whose actual length is 6 km and actual width is 900 meters?

Final Answer:

x =  4 cm
y =  0.6 cm

Step-by-step explanation:

$$\begin{gathered} a=6\text{km}\to \text{cm}=6\cdot 1000\cdot 100\text{cm}=600000\text{cm} \\ b=900\text{m}\to \text{cm}=900\cdot 100\text{cm}=90000\text{cm} \\ M=150000 \\ x=a/M=600000/150000=4\text{cm} \end{gathered}$$

$y=b/M=90000/150000=0.6\text{cm}$
