A blueprint for a cottage has a scale of 1:40

One room measures 3.4m by 4.8m.

Calculate the dimensions of the room on the blueprint.

 

Hello parpar!

 

\(w:3.4m=1:40\\ 40w=3.4m\)

\(w=\frac{3.4m}{40}\cdot \frac{100cm}{m}\)

\(w=8.5cm\)       on the blueprint

 

\(l=\frac{4.8m}{40}\cdot \frac{100cm}{m}\)

\(l=12cm\)         on the blueprint

 

greetings

laugh  !
