It is known that 15.6≤p≤15.8. find the possible values of the side of a square if p is the perimeter of the square.

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
