find perimeter of a trapezium wit 3 sides given and distance b/w parallel sides given

• The case can be of 2 types - the given parameters can be either the 2 parallel sides and one non-parallel side; or the 2 non-parallel sides and one of the parallel sides. along with the perpendicular distance b/w the 2 parallel sides.
  
  In both the cases we can use pythagoras theorem and find out the length by which the longer parallel side is longer than the other parallel side.
  Using sum addition or subtraction, we can find the 4th side.
  Then by adding all the 4sides we'll get the perimeter.

• use sine rule as the distance between parallel sides is given
