Question

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?

Answer 1

we have a relationship and we can use cross multiplication

where x is 2719km represented as centimeters

so find x

`\begin{gathered} x=(2719*3)/(100) \\ \\ x=81.57 \end{gathered}`

the shoreline will measure 81.57 cm
