    Let the breadth = x

    Length = 2x-8

    Perimeter = 2×(l+b)

    = 2×(x+2x-8)

    = 2×(3x-8)

    According to problem

    2×(3x-8)=56

    3x-8= \cancel\dfrac{56}{2}

    3x-8=28

    3x=28+8

    3x=36

    x=\cancel\dfrac{36}{3}

    \thereforeBreadth= x=12m

    \thereforeLength= 2x-8=2×12-8=24-8=16m

    breadth=x

    the length of a rectangle=2x-8

    the perimeter of the rectangle=34

    the perimeter of the rectangle=2(l+b)

    34 =2(l+b)

    34/2=l+b

    17=x+2x-8

    17+8=3x=x=25/3

    l=25/3

    b=2×25/3-8

    = 50/3-8

    =(50-24)/3=26/3
