    The answer to your question is L = 22; w = 15

    Step-by-step explanation:

    Data

    length = L

    width = w

    Perimeter = 74

    Condition

    w = L/2 + 4

    Formula

    P = 2L + 2w

    Substitution

    74 = 2L + 2 (L/2 + 4)

    Simplification

    74 = 2L + L + 8

    74 = 3L + 8

    74 - 8 = 3L

    3L = 66

    L = 66/3

    L = 22

    w = 22/2 + 4

    w = 11 + 4

    w = 15
