Answer 2

Answer:

Step-by-step explanation:

 Let the width of the rectangle be x.

 Let the length be 12+x.

 Then the perimeter of the rectangle is,

           =2(l+b)

            =2(x+12+x)

           =2(2x+12)

   60/2=2x+12

  30-12=2x

       18=2x

         x=9

Thus the width of the rectangle is 9cm.

The length of the rectangle is 21cm.
