The formula for the perimeter \(P\) of a rectangle is given by: 

where \(l\) is the length and \(w\) is the width.

Find the perimeter when \(l=8\) cm and \(w=5\) cm.

Given that the perimeter is \(30\) cm and the width is \(6\) cm, find the length.

The width is increased by \(3\) cm while the length remains the same.
Write a new expression for the perimeter in terms of \(l\).

The formula for the area \(A\) of a rectangle is:

If the area is \(48\) cm\(^2\) and the length is \(6\) cm, find the width.
