What is the size of the land that is Anne and Mark now use for farming in terms of square kilometers? (1 km^2 = 100 hectares)

Answer 1

Anne and Mark purchased three-fourth of 1250 hectares plot for large scale farming purposes.

3/4 * 1250 = 937.5 hectares

3 months later, they decide to let a fifth of their purchased land be used by a nearby construction

1/5* 937.5 = 187.5 hectares

937.5 - 187.5 = 750 hectares

Since 1km^2 = 100 hectares

100 h / 100 = 1 km^2

750 h / 100 = 7.5 km^2
