120 dm =............... cm

12cm = .................mm

2km 26m^2= ......m

320 cm ^2 = ....dm^2

2a = .....m^2

0,215 km ^2 = .....ha

7,4a = .......cm^2

Answer 1

120 dm =120 * 10cm = 1 200cm

12cm = 12 * 10mm = 120mm

2km 26m^2= ......m  ----  z tym przykładem coś nie tak jets

320 cm ^2 = 320 : 100 = 3,2dm^2

 

 

2a = 2 * 100m^2 = 200m^2

0,215 km ^2 =0,215 * 100ha = 21,5ha

7,4a =7,4 * 100m^2 = 740cm^2

Answer 2

120 dm = 120 * 10cm = 1200cm

12cm = 12 * 10mm = 120 mm

2km 26m^2 = 20000026 m^2

320 cm^2 = 320 * 0,01 dm^2 = 3,2 dm^2

 

2a = 2 * 100m^2 = 200m^2

0,215 km^2 = 0,215 * 100ha = 21,5 ha

7,4a = 7,4 * 1000000cm^2 = 7400000cm^2

 

Pozdrawiam i życzę powodzenia na matmie :)
