    Two sides are 3x longer than the shortest side. So, set up your problem like this.

    X = unknown length in centimeters

    3X = length of two longer sides

    1X = length of short side

    3x + 3x + 1x = 49

    7x = 49

    x = 7

    So, two longer sides are 21 centimeters each and the short side is 7 centimeters.

    21+21+7 = 49
