If a rectangle with a perimeter of 3.6 decimeters is increased by 5 centimeters in length and width, by how many square centimeters is the new rectangle larger than the original rectangle? (Hint: Drawing analysis shows that the increased area is the area of two small rectangles and the area of a small square.)
