    68.47 m

    Step-by-step explanation:

    Data provided:

    The shape of the yard as rectangular

    Length of the gate = 3.13 m

    Sides of the yard = 14.2 m

    Length of the yard = 21.6 m

    Therefore,

    The total length of the fence

    = Perimeter of the rectangular yard - Length of the gate

    or

    = 2 (Side of the yard + Length of the yard) - Length of the gate

    = 2 (14.2 + 21.6) - 3.13

    = 71.6 - 3.13

    or

    The total length of the fence = 68.47 m
