Explicație pas cu pas:
1,32ha-123,5dam²=13200m²+12350m²=25550m²
0,125km²+0,14dam²= 1250000000cm²+ 140000cm²= 1.250.140.000cm² (125014x10 la puterea a patra cm²)
deoarece: 0,125km²=12,5hm²=1250dam²=125000m²=12500000dm²= 1250000000cm² iar 0,14 dam²=14m²=1400dm²=140000cm²
5dam²+4320cm²-2,4m²+0,12km²=50000dm²+43,20dm²-240dm²+ 12.000.000dm²=12.049.803,20dm²
43,5m²-1243cm²+0,01dam²=4350dm²-12,43dm²+100dm²=4437,57dm²
0,142km²+42,35hm²=1420dam²+4235dam²=5655dam²
24dam²+36,25hm²+276325cm²=2400m²+ 362500m²+27,6325m² = 364927,6325m²
