For this case, the first thing you should do is take into account the following unit conversion:
 1 foot = 12 inches
 Therefore, the perimeter of the new window is given by:
 p = 2w + 2l
 Where,
 w: width
 l: long
 Substituting values:
 p = 2 * (3 + ((4 1/2) / 12)) + 2 * (4 + ((4 1/2) / 12))
 p = 15.5 feet
 Answer:
 The new perimeter of the window in feet is:
 p = 15.5 feet
