<PRE><B>Question 1013206</B>
.
The breadth of a rectangle is 3k cm. {{{highlight(Its)}}} 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, {{{highlight(it_is)}}} 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.
