    width is 16 m

    Step-by-step explanation:

    The perimeter of a rectangle is found by

    P = 2 (l+w)

    Substituting the values in

    46 = 2 (7+w)

    Divide each side by 2

    46/2 = 2/2 (7+w)

    23 = 7+w

    Subtract 7 from each side

    23-7 = 7-7+w

    16 = w

    width = 16 m

    Step-by-step explanation:

    If perimeter for a rectangle = 2x length + 2x width, then 2 x 7 = 14.

    46 - 14 = 32

    32/2 = 16

    Hence why 16 is the width.
