Question

314 cm² + 2 dm² = ... M²
1000 m² + 2 hm² =... Are
3000 m² + 250 are = ... Hektare
10 hektare + 1000 dam² = ... Km ²
0,14 hektare + 10 are =... Dm²

Answer 1

314 cm²=314 :100 =3,14m²
2 dm²=2 :10=0,2m²
3,14+0,2=3,34m²

1000m²=1000:10=100ARE
2Hm²=2×10=20are
100+20=120are

3000 m²=3000:100=30hektare
250are =250:10=25 hektare
30+25=55hektare

10 hektar=10:10=1km²
1000 dam²=1000:100=10km²
1+10=11km²

0,14 hektar=0,14×100=14Dm²
10are=10×100=1000Dm²
14+1000=1014dm²
