Question 251367: The length of a rectangle is fixed at 14cm. What widths will make the perimeter greater than 76cm?

      P = 2L + 2W

      P = 2(14) + 2W

      P = 28 + 2W

      P > 76

28 + 2W > 76

     2W > 76 - 28

     2W > 48

      W > 24 cm

Any widths greater than 24cm will make the perimeter greater than 76cm.
