    Step-by-step explanation:

    c - side of the square

    Formula: P = 4c.

    By substituting:

    15.6 ≤ 4c ≤ 15.8

    By dividing 4:

    3.9 ≤ c ≤ 3.95.

    So the possible values of the side of square is from 3.9 to 3.95.

    15.6 ≤ P ≤ 15.8

    The perimeter of a square is found by multiplying the length of one side by 4, so P can be rewritten as 4s (4 times side length).

    Now the equation becomes:

    15.6 ≤ 4s ≤ 15.8

    Now we can solve for the values of S by dividing all terms by 4:

    15.6 / 4 ≤ 4s / 4 ≤ 15.8 / 4

    Simplify:

    3.9 ≤ s ≤ 3.95

    The side lengths are between 3.9 and 3.95
