# Painter 3

Dad want to paint wall high 250 cm wide and 230 cm with wallpaper. How many meters must buy wallpaper if wallpaper width is 60 cm?

Result

x =  9.6 m

#### Solution:

$a=250 \ cm \rightarrow m=250 / 100 \ m=2.5 \ m \ \\ b=230 \ cm \rightarrow m=230 / 100 \ m=2.3 \ m \ \\ s=60 \ cm \rightarrow m=60 / 100 \ m=0.6 \ m \ \\ \ \\ S=a \cdot \ b=2.5 \cdot \ 2.3=\dfrac{ 23 }{ 4 }=5.75 \ \text{m}^2 \ \\ \ \\ x=S/s=5.75/0.6 \doteq \dfrac{ 115 }{ 12 } \doteq 9.5833 \doteq 9.6 \ \text{m}$
