Expert Answer
suppose there is an U shaped wire, in which BD is another wire which is movable threough it.
suppose you have dipped it into soap solution and stretched  BD by x distance.there is always a force acting on BD ie l length due to surface tension.
work done in doing so=forcex dist
                               =Tlx        as surface tension T=F/l
this work done is equal to the increase in energy / surface energy.
so     T lx=increase in surface energy
so  T=increase in surface energy/lx
        =increase in surface energy/increase in area
