The shoreline of Great Bear Lake is approximately 2719 km. If a map is drawn with a scale of 3 cm:100 km, how long would the shoreline be on the map?

Respuesta :

we have a relationship and we can use cross multiplication

[tex]\begin{gathered} 3\operatorname{cm}\longrightarrow100\operatorname{km} \\ \text{Xcm}\longrightarrow2719\operatorname{km} \end{gathered}[/tex]

where x is 2719km represented as centimeters

so find x

[tex]\begin{gathered} x=\frac{2719\times3}{100} \\ \\ x=81.57 \end{gathered}[/tex]

the shoreline will measure 81.57 cm
