.
<pre>
When 4 cm was taken from the length and added to the breadth, the perimeter did not changed, correct ?


Hence, the square has THE SAME PERIMETER as the rectangle, i.e. 84 cm.


It means that each side of the square is {{{84/4}}} = 21 cm.


The the length of the original rectangle was 21+4 = 25 cm,  while the breadth of the original rectangle was 21-4 = 17 cm.


<U>Answer</U>.  The dimensions of the original rectangle were 25 cm (length) and 17 cm (breadth).


<U>Check</U>.   25 + 17 + 25 + 17 = 2*25 + 2*17 = 50 + 34 = 84 cm.  ?Correct !
