Problema Solution
A rectangle 8 feet by 6 feet has a border of uniform width around the inside of all four edges. If the border has an area of 33 square feet, how wide is the border?

Let 'w' represent the width of the border, w>=0.
The area of the border is equal to the total area with the border minus the area without the border:
(8 + 2w)*(6 + 2w) - 8*6 = 33
