ubah ke satuan 5km2=….haktare, 314cm2+2dm2=….m2, 1.000m2+2hm2=….are, 3.000m2+250are=…hektare, 10hektare+1.000dam2=…km2, 0,04hektare+10are=….dm2, tolong saya dengan caranya?

5km2=5×100=500ha

314cm2+2dm2=314:10000=0.0314
=2:100=0,02
0,0314+0,02=0,0514m2

1000m2+2hm2=1000:100=10
=2×100=200
10+200=210are

3000m2 + 250 are =3000:1000=3
=250:100=2,5
3+2,5=5,5 ha

10 ha + 1000 dam2 =10:100=0,1
=1000:10000=0,1
0,1+0,1=0,2km2

0,04 ha + 10 are = 0,04×1000000=40000
10×10000=100000
1000000+40000=140000dm2
