<PRE><B>Question 332710</B>
Let the width of the rectangle be x
and the length is  9 centimeters more than half the width
that is
length = 9+x/2
given perimeter =60cm
perimeter =2(l+w)
 60 =2(9+x/2+x)
60=2(9+3x/2)
60 =18+2*3x/2
60 =18+3x
60-18=3x
42=3x
x=14
width =14cm 
length =9+x/2 
         =9+14/2
       =9+7
     =16cm

length=16cm and width =14cm</PRE>
