zamień na podane wartości po wielokropku

1dm2(kwadratowy)..............mm2

2m2........cm2

4a.........dm2

25ha..............m2

50a................m2

2km2........a

0,3dm2..........mm2

42m2.....................km2

5,1 cm2...........................mm2

4891km2..................ha

3a..............ha

25mm2................m2

Answer 1

1dm2 = 1 * 10000mm2 = 10000mm2

2m2 = 2 * 10000cm2 = 20000cm2

4a = 4 * 10000dm2 = 40000dm2

25ha = 25 * 10000m2 = 250000m2

50a = 50 * 100m2 = 5000m2

2km2 = 2 * 1000000m2 = 2 * 1000000 * 0,01a = 20000a

 

0,3dm2 = 0,3 * 10000mm2 = 3000mm2

42m2 = 42 * 0,000001km2 = 0,000042km2

5,1cm2 = 5,1 * 100mm2 = 510mm2

4891km2 = 4891 * 1000000m2 = 4891 * 1000000 * 0,0001ha = 489100ha

3a = 3 * 0,01ha = 0,03ha

25mm2 = 25 * 0,000001m2 = 0,000025m2

Myślę, że dobrze :)
