The perimeter of a rectangle is given as twice the sum of its length and breadth. The breadth of a rectangle is thrice its length, $y$. Express the perimeter in terms of $y$.

Given the length of rectangle = $y$; breadth = $3y$

To find the perimeter of the rectangle in terms of $y$

Solution:

Perimeter of rectangle = 2(length + breadth)

= $2(y + 3y)$ 

=$2(4y)$

= $8y$

So perimeter of the rectangle in terms of y =$8y$
