    Answer: 16x - 30

    Step-by-step explanation:

    Determine values of L and W

    We know that the perimeter can be found by the equation p = 2L + 2W where L is the length and W is the width

    L = 3x-4

    W = 5x-11

    Plug in the values of L and W into the equation and solve

    p = 2L + 2W

    p = 2 (3x - 4) + 2 (5x - 11)

    p = 6x - 8 + 10x - 22

    p = 16x - 30

    (16x - 30) units

    Step-by-step explanation:

    Perimeter = 2[length + width]

    = 2[3x-4 + 5x-11]

    = 2[8x - 15]

    = 16x - 30
