Let w be the page width, in inches.


Then its length is (w+3) inches.


The printed area has dimensions in 2 = 1 + 1 inches less. Therefore, the equation for the printed area is


(w-2)*(w+1) = 80.


w^2 -w - 82 = 0.


Solve it using the quadratic formula.


 =  =  = .


Only positive value of w makes sense, which is  w =  = 9.57 inches.


Answer.  The dimensions of the page are  9.57 and 12.57 inches.


Check.   (9.57-2)*(12.57-2) = 80.0 square inches.  The solution is correct.
