    15 inches.

    Step-by-step explanation:

    Let the length of each side of square be x

    perimeter of square is given by 4*side/

    Thus, perimeter of square iwh side x = 4x

    Given

    length of each side of a square increases by 2.5

    new side length of square = x + 2.5

    New perimeter of the square = 4 * (x + 2.5) = 4x + 10

    given that new perimeter = 70 inches

    Thus,

    4x + 10 = 70

    4x = 70 - 10 = 60

    x = 60/4 = 15

    Thus, length of each side of original square was 15 inches.
