Answer:
The length of the sides of the square is 9.0015
Step-by-step explanation:
Given
The diagonal of a square = 12.73
Required
The length of its side
Let the length and the diagonal of the square be represented by L and D, respectively.
So that
D = 12.73
The relationship between the diagonal and the length of a square is given by the Pythagoras theorem as follows:

Solving further, we have

Divide both sides by 2


Take Square root of both sides


Reorder

Now, the value of L can be calculated by substituting 12.73 for D




(Approximated)
Hence, the length of the sides of the square is approximately 9.0015
