    Answer:

    8 inches

    Step-by-step explanation:

    Let w represent the width.

    If the length is 14 inches longer than the width, it can be represented by w + 14.

    Use the perimeter formula, p = 2l + 2w. Plug in 60 as the perimeter and w + 14 as l, then solve for w:

    p = 2l + 2w

    60 = 2(w + 14) + 2w

    60 = 2w + 28 + 2w

    60 = 4w + 28

    32 = 4w

    8 = w

    So, the width is 8 inches
