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?


x =  9.6 m


a=250 cmm=250/100 m=2.5 m b=230 cmm=230/100 m=2.3 m s=60 cmm=60/100 m=0.6 m  S=a b=2.5 2.3=234=5.75 m2  x=S/s=5.75/0.6115129.58339.6 ma=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}
