Polecam sobie wyobrazić ile to jest np metr kwadratowy.
Jest to powierzchnia kwadratu o bokach 100cm na 100cm bo 1m=100cm więc 1[tex]m^{2}[/tex]=10000[tex]cm^{2}[/tex]
1[tex]dm^{2}[/tex] powierzchnia kwadratu o boku 1dm*1dm czyli 0.1m*0.1m
1[tex]dm^{2}[/tex]=0.01[tex]m^{2}[/tex] czyli 1[tex]m^{2}[/tex]= 100[tex]dm^{2}[/tex]
a) 12[tex]m^{2}[/tex]= 1200[tex]dm^{2}[/tex]
II) 3,6[tex]dm^{2}[/tex]= 0.036[tex]m^{2}[/tex]
III) 4,6[tex]m^{2}[/tex]=46000[tex]cm^{2}[/tex]
IV) 0.56[tex]dm^{2}[/tex]= 0.56*0.01=0.0056[tex]m^{2}[/tex]
