The perimeter of a rectangular writing pad is 28 inches. The length is 1 inch less than twice the width. What did I do wrong in setting the problem up?
P= 2l + 2w, length is 2x-1
-------
That's good so far.
width = x and length = 2x-1
--------
Now substitute to get:
28 = 2(2x-1)+2x
Then you can solve for x and for 2x-1.
cheers,
Stan H.
