Area of larger rectangle = PQ   x   12   =  66     then PQ = 5.5

 

BC = 5.5      Perimeter of smaller rectangle   = 30  =   2 *BC + 2*AB

                                                                           30 = 2(5.5) + 2 AB           You can take it from here !    cheeky

PQ=5.5

 

So, 30 minus 5.5 times 2 is 19, 

19/2 will be our answer.
