To convert meters to centimeters, you multiply by 100.

So, 6.07 m = 6.07 * 100 cm = 607 cm.

To convert square meters to hectares, you divide by 10,000.

So, 234.78 m2 = 234.78 / 10,000 ha = 0.023478 ha.

To convert square kilometers to hectares, you multiply by 100.

So, 45 km2 = 45 * 100 ha = 4500 ha.

To convert decameters squared to meters squared, you multiply by 100.

So, 56 dam2 = 56 * 100 m2 = 5600 m2.

To convert square meters to meters squared, you add the two values.

So, 56 dam2 20m2 = 5600 m2 + 20 m2 = 5620 m2.
