Answer 1

2ha=2*100a=200a
1,5ha=1,5*100=150a
150ha=150*0,01km²=1,5km²
112a=112*0,01ha=1,12ha
15,4a=15,4*0,01ha=0,154ha
12km²=12*100ha=1200ha


Zamien na m²:
10mm²=10*0.000001m²=0,000010m²
14,50mm²=14,5*0,00001m²=0,0000145m²
21,2233cm²=21,2233*0.0001m²=0,00212233m²
2cm²=2*0,0001m²=0,0002m²
0,00019dm²=0,00019*0,01m²=0,0000019m²
0,00000009dm²=0,00000009*0,01m²=0,0000000009m²
15km²=15*1000000m²=15000000m²
15,83km²=15,83*1000000m²=15830000m²
21,2233km²=21,2233*1000000m²=21223300m²
2km²=2*1000000m²=2000000m²
0,00019km²=0,00019*1000000m²=190m²
0,00000009km²=0,00000009*1000000m²=0,09m²


Zamien na km²:
9mm²=9*0.000000000001km²=0,000000000009km²
145,36cm²=145,36*0.0000000001km²=0,000000014536km²
21,5mm²=21,5*0.000000000001km²=0,0000000000215km²
19dm²=19*0.00000001km²=0,00000019km²
2,59m²=2,59*0.000001km²=0,00000259km²
0,00005m²=0,000005*0.000001km²=0,00000000005km²
