Răspuns:

Explicație pas cu pas:

1 m² = 100 dm²= 10000 cm² = 1000000 mm²

1 m² = 0,01 dam² = 0.0001 hm² = 0,000001 km²

1 ha =  10000 m²

1)

3450,256 m² =  3450,256 : 10000 hm² =  0,3450256 hm²

3450,256 m²  =  3450,256 : 100 dam² =  34,50256 dam²

3450,256 m² =  3450,256 x 100 dm² =  345025,6 dm²

3450,256 m² =   3450,256 x 10000 cm² =  34502560 cm²

2)

7000000 cm² = 7000000 : 10000 m² = 700 m²

3 km² = 3 x 1000000 m² = 3000000 m²

725 dm² = 725 : 100 dm² = 7,25 m²

436 dam² = 436 x 100 = 43600 m²

18 ha  = 18 x 10000 m² = 180000 m²

14250 cm² = 14250 : 10000 m² = 1,4250 m²

36042500 mm²=  36042500 : 1000000 m² = 36,042500 m²
