if the land area of earth was divided equally for each person on the planet, about how much woulf you get
Hoochie [10]

Answer:

<em></em>Unit\ Area = 0.067\ km^2<em></em>

<em></em>

Step-by-step explanation:

<em>To solve this question, we need the area and population of the earth</em>

<em></em>Area = 510.1 million\ km\²<em></em>

<em></em>Population = 7.594\ billion<em> ---- 2018 population</em>

<em></em>

<em>Next is to divide the area by population;</em>

<em></em>Unit\ Area = \frac{Area}{Population}<em></em>

<em></em>Unit\ Area = \frac{510.1\ million}{7.594\ billion}<em></em>

<em></em>

<em>Convert to digits</em>

<em></em>Unit\ Area = \frac{510.1 * 1000000}{7.594 * 1000000000}<em></em>

<em></em>

<em>Divide numerator and denominator by 1000000</em>

<em></em>Unit\ Area = \frac{510.1}{7.594 * 1000}<em></em>

<em></em>Unit\ Area = \frac{510.1}{7594}<em></em>

<em></em>Unit\ Area = 0.06717145114<em></em>

<em></em>Unit\ Area = 0.067\ km^2<em> -- Approximated</em>

<em></em>

<em>This means that;</em>

<em>I'll get about 0.067km² area of the earth</em>
