1. a) 2,80m² = 280dm² = 28000cm² = 2800000mm²

   b) 1,22m² = 0,0122dam² = 0,000125hm² = 0,00000125km²

   c) 5m² = 500dm² = 50000cm² = 5000000mm²

   d) 1,7m² = 170dm² = 17000cm² = 1700000mm²

   e) 10m² = 1000dm² = 10000cm² = 10000000mm²

   f) 25m² = 2500dm² = 250000cm² = 25000000mm²

   Vì 1m² = 100dm² = 10000cm² = 1000000mm²

       1m² = 0,01dam² = 0,0001hm² = 0,000001km²
