What is the quantity which is measured by the area occupied below the velocity - 'time graph?

Answer 1

   velocity time graph shows variation of the velocity wrt time.

   Suppose the velocity V is constant.  Then the graph is a horizontal line.  At any point of time T, the area enclosed is a rectangle  and is = V T.

   The area occupied below the curve or graph  will be the distance traveled by the body in time T.
       This is true what ever way the velocity changes wrt time.
