Answer 1

Explicație pas cu pas:

4. Calculaţi:

a) 200 m² +1 km² +30 hm^2=

200m² + 1000000m^2 + 300000m^2 =

1300200m^2

b) 350 m+4000 cm+3 km=

35000cm + 4000 cm + 300000cm =

339000 cm

c) 1 m +40 mm +200 dam =

1000 mm + 40 mm + 200000 cm =

201040 mm

d) 2000 mm +5,5 m +40 hm =

2 m + 5,5 m + 4000 m =

4007,5 m
