    20*6 - 120

    20*6 = 120

    19 * 6 = 114

    Step-by-step explanation:

    Call x the scale factor.

    20x + 19x + 20x = 354 Add the left side together.

    59x = 354 Divide by 59

    59x/59 = 354/59 Combine and cancel

    x = 6

    The lengths of the sides are

    20 * 6 = 120

    19 * 6 = 114

    20 * 6 = 120
