    Thanks Yogita, but I think that double fence means on the both sides of path. As the gate is only on one side so we have to minus length of three gates from total fence only one time and the answer is 490m

    A gardener has to put a double fence all around a triangular path with sides 120m, 80m and 60m.

    In the middle of each side there is a gate of width 10m.

    The perimeter of triangle = Sum of all sides

    = 120+80+60 = 260 m

    Now , the length of wire needed for fence =  2 x ( Perimeter of triangle - 3(10))

    = 2 x(260-30) = 2 x (230) = 460 m

    5Thank You
