    The equation can be expressed as;

    x+y=71 where,

    Lengths of two equal sides=x=22 m

    Lengths of longer side=y=27 m

    Step-by-step explanation:

    The total perimeter can be expressed as;

    Total perimeter=Total length of the equal sides+total length of the longer side

    where;

    Total perimeter=71 m

    Total length of each of the equal sides=x m

    Total length of longer side=y = (x+5) m

    replacing;

    x+y=71 ... equation 1

    71 = (2*x) + (x+5)

    2 x+x=71-5

    3 x=66

    x=66/3

    x=22 m

    y=x+5=22+5=27 m

    Lengths of two equal sides=22 m

    Lengths of longer side=27 m

    Equation;

    x+y=71
