Answer:

The length of its diagonal is
27.01\ m

Explanation:

Let

b------> the length side of the square

d-----> the diagonal of the square

we know that

The perimeter of the square is


P=4b


P=76.4\ m

Find the value of b


4b=76.4


b=76.4/4=19.1\ m

Applying the Pythagoras theorem find the length of the diagonal


d^(2)=19.1^(2)+19.1^(2)\\ \\d^(2)=729.62\\ \\ d=27.01\ m
