Question

If a person is mowing along the boundary of a square
shaped field having the length of 10m. Calculate
the value of distances and displacements when he covers only a single side of the field. .​

Answer 1

Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
The value of distances and displacements when he covers only a single side of field is 1224567889
