proszę o pomoc na dzisiaj ...

Answer 1

1dm2=10x10cm=100cm2

1cm2=10x10mm=100

1,2dm2=120cm2

37mm2=0,37cm2

2,5m2=2500cm2

13,5m2=13500cm2

450m2=45000dm2

4,5m2=450dm2

25m2=2500dm2

14,3m=1430dm2

 

450m2=4,5a

2,5km2=25000ar

3,5ha=3500ar

250m2=2,5a

 

 

licze na naj :) pliss :) to cię nic nie kosztuje a mi pomoże :)

Answer 2

1,2dm2 = 120cm2

37mm2 = 0,37cm2

2,5m2 = 25 000cm2

13,5m2 = 135 000cm2

450m2 = 45 000dm2

4,5m2 = 450dm2

25m2 = 2 500dm2

14,3m2 = 1 430dm2

450m2 = 4,5ar

2.5km2 = 25 000ar

3,5ha = 350ar

250m2 = 2,5ar
