1cm²= 1cm × 1cm = 10mm × 10mm = 100mm²
1cm² = 1cm × 1cm = 0,1dm × 0,1dm = 0,01dm²
1cm² = 1cm × 1cm = 0,01m × 0,01m =0,0001m²
1mm² = 1mm × 1mm = 0,1cm × 0,1cm = 0,01cm²
1mm² = 1mm × 1mm = 0,01dm × 0,1dm = 0,0001dm²
1mm² = 1mm × 1mm = 0,001m × 0,001m = 0,000001m²
1dm² = 1dm × 1dm = 10cm × 10cm = 100cm²
1dm² = 1dm × 1dm = 100mm × 100mm = 10000mm²
1dm² = 1dm × 1dm = 0,1m × 0,1m = 0,01m²
1m² = 1m × 1m = 100cm × 100cm = 10000cm²
1m² = 1m × 1m = 1000mm × 1000mm = 1000000mm²
1m² = 1m × 1m = 10dm × 10dm = 100dm²
