<PRE><B>Question 609884</B>
Suppose that we have a rectangular book cover. If the width is increased by 2 centimeters, and the length is decreased by 1 centimeter, then the area is increased by 28 square centimeters. However, if the width is decreased by 1 centimeter and the length is INCREASED by 2 centimeters, then the area is increased by 10 square centimeters. Find the dimensions of the book cover. 

(W+2)(L-1)= 28
(W-1)(L+2)= 38 
----
Note that the area was INCREASED by 10 cm.
