9 x 13 = 117 square inches
When a square paper is folded vertically to form a rectangle with a perimeter of 39 inches, the length of the rectangle is 19.5 inches (half of the perimeter). Since the length of the rectangle is the same as the side length of the original square, the area of the original square can be calculated as the square of the side length, which is 19.5 inches squared, equaling 380.25 square inches.
117 square inches (13 x 9 = 117)
11' x 13' = 20,592 square inches.
14,976 square inches.
