169 square inches.
Folding the square in half leaves 2 edges of the original side length and two of half the side length. Therefore:
perimeter = side + 1/2 side + side + 1/2 side
= 3 sides
⇒ 3 sides = 39 inches
⇒ 1 side = 39 inches ÷ 3
= 13 inches
⇒ area_original_square = 13 inches x 13 inches
= 169 square inches.
