Zamień na m²
a) 0,5km²= 0,5*1000000m² = 500000m²
1km² = 1000000m² (1km = 1000m, 1km² = 1000m*1000m)
b) 441a =44100m²
1a = 100m² (1 ar to kwadrat o boku 10m)
c) 6dm² = 6*0,01m² = 0,06m²
1dm² = 0,01m² (1m² =100dm², 1m = 10dm, 1dm = 0,1m)
d) 3,2ha = 3,2*10000m² = 32000m²
1ha = 100a = 10000m² (1 hektar to kwadrat o boku 100m)
