If every person in the world were to own an equal share of the earth’s land, the number of square miles each person would  have is: b)0.00512mi^2/person.

Square miles

First step

Surface area of earth=4πr²

Surface area  of earth=4π(3959)²

Surface area  of earth=196,961.284 miles²

Second step

Suitable land area=20%×196,961.284

Suitable land area=39,392,256.87

Third step

Square miles=Suitable land area/Number of people on earth

Square miles=39,392,256.87/7700000000

Square miles=0.005115

Square miles= 0.00512 mile²/person (Approximately)

Therefore the number of square miles each person would  have is: b)0.00512mi^2/person.
