Question

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.

Answer 1

the answer is 3.9 ≤ a ≤ 3.95

Explanation:

Answer 2

3.9 ≤ a ≤ 3.95

Explanation:

a - side of the square

Formula: P = 4a.

By substituting:

15.6 ≤ 4a ≤ 15.8

By dividing 4:

3.9 ≤ a ≤ 3.95.

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