  1. Step-by-step explanation:

    A.T.Q(According to the question)

    3:4:5=36 cm (let 3:4:5 be 3x,4x,5x)

    3x+4x+5x=36 cm

    12x=36 cm

    x=36/12

    x=3

    3x=3(3)=9

    4x=4(3)=12

    5x=5(3)=15

    Verification

    Perimeter of triangle=side 1+side 2+side 3

    Perimeter of triangle=9+12+15

    Perimeter of triangle=36 cm
