<PRE><B>Question 936410</B>
length of window  = 5 ft 2 in
width  = 3 ft 5 in
perimeter  = 2*( length+width)
           = 2*(5ft 2 in +3 ft 5 in)
              = 2*(8 feet 7 in)
                = 2*8 feet +2*7 inches
               = 16 feet +14 inches
                             but 12 inches  = 1 foot
           = 16 feet +12 inches+2 inches
          = 16feet+1 foot + 2 inches
         = 17 feet 2 inches
Result : Perimeter  =  17 ft 2 in
