Answer 3

To convert the given measurements, we can use the following conversion factors:

1 cm^2 = 100 mm^2 1 ha = 10,000 m^2 1 cm^2 = 0.0001 m^2 1 kg = 1000 g 1 century = 100 years 1 cm = 10 mm

Using these conversion factors, we can perform the conversions:

5 cm^2 = 5 * 100 mm^2 = 500 mm^2 221 ha = 221 * 10,000 m^2 = 2,210,000 m^2 20 cm^2 = 20 * 0.0001 m^2 = 0.002 m^2 60,020 kg = 60,020 * 1000 g = 60,020,000 g 45,000 years = 45,000 / 100 = 450 centuries 45,000 cm = 45,000 * 10 mm = 450,000 mm

So the conversions are as follows:

5 cm^2 = 500 mm^2 221 ha = 2,210,000 m^2 20 cm^2 = 0.002 m^2 60,020 kg = 60,020,000 g 45,000 years = 450 centuries 45,000 cm = 450,000 mm
