So , let's find the side of the square :-

Hence the side of square is 8cm .

Now , breadth of rectangle will be 8cm.

Now its given that the area of rectangle is 1½ times the area of square. So ,

Hence side will be :-

Hence the lenght of rectange is 12cm .

Now , the perimeter of the given figure will be ,
