Answer 1

The perimeter of a standard-sized rectangular rug is 28ft. The length is 2ft longer than the width. What is the width?

 

Now, here's a wonderful opportunity to use Algebra, and the definition of perimeter.

 

You know that P = 28 ft and also that it equal to 2(L+W), by formula.

 

Let's note that L = 2+W.  Substitute for L in the above formula and you'll find what numeric value W must be, and then L will also be known to you.
