The perimeter of a square is 56 cm. what is the approximate length of its diagonal? 10.6 cm 14.0 cm 15.0 cm 19.8 cm

The approximate length of its diagonal is:

                                    19.8 cm

We know that for any square with a side length of s units.

The diagonal of a square has length:

Also, the perimeter of a square is the sum of all the side lengths of a square.

i.e.

Here we are given:

Perimeter of square= 56 cm.

i.e.
