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
