The perimeter of a square is 56 cm. what is the approximate length of its diagonal

20

Step-by-step explanation:

To solve this, we have to multiply one of the side lengths by the square root of 2.

Since it is a square, we can deduce that all of the side lengths are equal, and us finding one of the side lengths is as simple as dividing 56 by 4.

56/4=14

Now, multiply.

14*square root of 2 is 19.7989898732 or 20.

The length of the diagonal of the square is 20.
