The breadth of a rectangle is 3k cm. length is 4 times its breadth.
Express the perimeter of the rectangle in terms of k in the simplest form. ( The k is not 1000, an algebra letter)
------------------------------------------------------------

If the breadth is 3k cm, then its length is 4*3k = 12k cm, according to the condition.

The perimeter is the sum of four sides, i.e.
3k + 12k + 3k + 12k = 30k centimeters.
