The Math / Science

The picture shows a clip from Google Maps (maps.google.com).  If you turn on the satellite feature, you can see the features of land.  If you right click on a corner you will see the small menu with the option to "Measure distance".  This lets you click a path.  If you notice, the graphic clicks the path that encloses a field.  When you enclose an area, Google provides a calculation of the area in square meters.  In this case, it was 4,662.07 m².  But what is that in acres?  This calculator converts square meters to acres.  In our example, that turned into 1.152 acres.
