Tomtit [17]

Answer:

1 cm^2 = 100 mm^2

9 cm^2 = 900 mm^2

5.2 cm^2 = 520 mm^2


1 dm^2 = 100 cm^2

17 dm^2 = 1700 cm^2

4.3 dm^2 = 430 cm^2


1 m^2 = 10000 cm^2

7 m^2 = 70000 cm^2

2.5 m^2 = 25000 cm^2


1 km^2 = 1000000 m^2

50 km^2 = 50000000 m^2

8.5 km^2 = 8500000 m^2

Step-by-step explanation:

1 cm = 10 mm

1 cm^{2} = 10×10 mm^{2} = 100 mm^{2}

9 cm^{2} = 9×100 mm^{2} = 900 mm^{2}

5.2  cm^{2} = 5.20×100 mm^{2} = 520 mm^{2}


1 dm = 10 cm

1 dm^{2} = 10×10 cm^{2} = 100 cm^{2}

17 dm^{2} = 17× 100 cm^{2} = 1700 cm^{2}

4.3 dm^{2} = 4.3 × 100 cm^{2} = 430 cm^{2}


1 m = 100 cm

1 m^{2} = 100×100 cm^{2} = 10000 cm^{2}

7 m^{2} = 7×10000  cm^{2} = 70000 cm^{2}

2.5 m^{2} = 2.5×10000 cm^{2} = 25000 cm^{2}


1 km = 1000 m

1 km^{2} = 1000×1000 m^{2} = 1000000 m^{2}

50 km^{2} = 50×1000000 m^{2} = 50000000 m^{2}

8.5 km^{2} = 8.5×1000000 m^{2} = 8500000 m^{2}
