Question

 Given a rectangle that is 48 cm longer than it is wide express the perimeter in centimeters of a rectangle in terms of its width W

Answer 1

really, Amanda from Ames, I believe that you must have been taught enough to attempt this problem yourself.

 

As always, draw said rectangle. Label its width W and then label its Length W + 48.  There are two 'widths' and two 'Lengths' in the rectangle.

 

Using the definition of perimeter, add up its four sides and combine like terms. Then you have the answer!

 

I emphasize that this should have been tackled by you, so that you learn the idea of attacking a problem with what you know. Only then can you be self-sufficient.
