    Answer:

    Answer is 4 because

    4x+5x+ 3x=12x

    12x=48

    x=48/12

    x=4

    Lengths of the sides are 12cm, 16cm and 20 cm.

    Step-by-step explanation:

    The sides are in the ratio 3:4:5.

    Let us take the three sides to be 3x,4x and 5x.

    3x+4x+5x=48 (Sum of the sides of the triangle = perimeter of the triangle)

    12x=48

    x=4

    Therefore,

    First side = 3x = 3*4 = 12cm

    Second side = 4x = 4*4 = 16cm

    Third side = 5x = 5*4 = 20cm

    hope it helps.
