Answer:
The answer to your question is 0.057 ha
Step-by-step explanation:
Data
Kilocalories needed for a person per day = 2450
Kilocalories produced per hectare = 15737000
Process
1.- Calculate the number of kcal needed per a person for a year
2450 kcal ----------------- 1 day
x ----------------- 365 days
x = (365 x 2450) / 1
x = 894250 kcal
2.- Calculate the amount of land needed
15737000 kcal ------------- 1 ha
894250 kcal ------------ x
x = (894250 x 1) / 15737000
x = 0.057 ha
