Ile to jest 27a = m² 75km² = ha 30ha = m² 4dm² = mm²​



Odpowiedź :

[tex]1ha = 100a[/tex]

[tex]1a = 100 {m}^{2} [/tex]

[tex]27a = 27 \times 100 = 2700 {m}^{2} [/tex]

[tex]75 {km}^{2} = 75 \times 1000000 {m}^{2} = 75000000 {m}^{2} = 7500ha[/tex]

[tex]30ha = 3000a = 300000 {m}^{2} [/tex]

[tex]4 {dm}^{2} = 4 \times 100 {cm}^{2} = 400 {cm}^{2} = 400 \times 100 {mm}^{2} = 40000 {mm}^{2} [/tex]

Szczegółowe wyjaśnienie:

27a = 27*100 m²= 2700 m²

75km² = 75*100 ha=7500 ha

30ha = 30*10 000 m² =300 000 m²

4dm² =4*10 000 mm²=40 000 mm²​
