The length of a rectangle is 3 x its breadth.
If the perimeter is 192 cm find
--------------
Equation:
length = x cm
breadth = 3x cm
--------------------
Perimeter = 2(length + bredth)
192 = 2(x + 3x)
96 = 4x
24 cm = x (length)
3x = 72 cm (bredth)

Hi,
.
2L + 2w = 192cm
L + w = 96cm
3w + w = 96cm
4w = 96cm
w = 24cm and L = 72cm
and...checking
L + w = 96cm
