Question

5 m2+2dm2+140000cm2=
0,12dam2-1200dm2=
45,2m2-541dm2+0,1dam2=

Answer 1

Resposta:

Explicação passo a passo:

5m²+2dm²+140000cm²=

2dm²:100=0,02m²

140000cm²:10000=14m²

5m²+0,02m²+14m²=

19,02m²

0,12dam²-1200dm²=

0,12x100=12m²

1200dm²:100=12m²

12m²-12m²=

0

45,2m²-541dm²+0,1dam²=

541dm²:100=5,41m²

0,1dam²x100=10m²

45,2m²-5,41m²+10m²=

39,79 m²+10m²=

49,79m²
