Odpowiedź:
[tex]a) \ 300 \ dm^{2} = 300\times 0,01 \ m^{2} = 3 \ m^{2}\\\\b) \ 9 \ 000 \ dm^{2} = 9 \ 000\times0,01 \ m^{2} = 90 \ m^{2}\\\\c) \ 80 \ 000 \ cm^{2} = 80 \ 000\times0,0001 \ m^{2} = 8 \ m^{2}\\\\d) \ 500 \ 000 \ cm^{2} = 500 \ 000\times 0,0001 \ m^{2} = 50 \ m^{2}[/tex]
Szczegółowe wyjaśnienie:
[tex]1 \ dm^{2} = 1 \ dm\times 1 \ dm = 10 \ cm \times 10 \ cm = 0,1 \ m\times 0,1 \ \m = 0,01 \ m^{2}\\\\1 \ m^{2} = 1 \ m \times 1 \ m = 100 \ cm\times 100 \ cm = 10 \ 000 \ cm^{2}\\1 \ cm^{2} = 0,0001 \ m^{2}[/tex]
