    Answer: First side is 40.5 meters. Second side is 121.5 meters. The third side is 159.

    Step-by-step explanation:

    x + 3x + 4x - 3 = 321

    8x - 3 = 321

    +3 + 3

    8x = 324

    x = 40.5

    Second Side: 3 (40.5) = 121.5

    Third side: 4 (40.5) - 3 = 159

    Check: 159 + 121.5 + 40.5 = 321
