Answer:
Amount of land = 0.056 hectares
Step-by-step explanation: Given that
An average person in the country needs 2,450 kilocalories / day. That is
A person in a day takes 2450 kilocalories
The average number of kcal per hectare(ha) produced from available food in the country is 15,737,000 kcal/ha.
So in one day per person, we have
15737000 = 2450/hec
Hectare = 2450/15737000
Hectare = 1.5568 × 10 -4
The amount of land that would be needed to produce enough kilocalories to feed a person for one year in this developing country will be
Calculated hectare × 365.25
Hectare = 1.5568 × 10 -4 × 365.25
Amount of land = 0.056 hectares
