title: I need to calculate the area of each country
body: <p>I am using the naturalearth_lowres pre-set map of geopandas and I need the area in km² of each country for further calculation. I have tried several solutions I found in the internet, but none of them worked for me.</p>
  
  <p>One of he solutions that did not work is <a href="https://gis.stackexchange.com/questions/218450/getting-polygon-areas-using-geopandas">this one</a>. The values I get from this calculation are not fitting the real values at all (compared them with values from wikipedia).</p>
  
  <p>I just need some sort of a formula for the area.</p>
