    Given
    Perimeter =132cm
    Let breadth be x
    So length be x+6
    So
    2(l+b)= perimeter
    2(x+x+6)=132
    2(2x+6)=132
    4x+12=132
    4x=132-12
    4x=120
    x=120/4
    x=30
    I hope this helps

    Answer:

    15

    Step-by-step explanation:

    given perimeter=132

    and perimeter of rectangle is 2(l+b)

    so 2(l+b)=132 that =l+b=66

    and let breadth=x then length is 6cm more than the 3times the breadth so length =3x+6

    so l+b=66

    (3x+6)+x=66

    4x+6=66

    4x=66-6

    4x=60

    so x=60/4=15
