Let the length of the rectangle be 4x metre and its breadth be 3x metre.
∴   (4x) x  (3x) = 192
rightwards double arrow space space straight x squared space equals space 192 over 12 space equals space 16 space space rightwards double arrow space space straight x space equals space 4
∴  Perimeter = 2(length + breadth)
            = 2(4x + 3x) = 14x
            = 14x = 14 x 4 = 56 metre
