Question

The side of a square is 25 cm . Find the length of its diagonal correct to 2 decimal places.

Answer 1

Answer:35.35 cm

Step-by-step explanation:

Length of each side of the square,a=25cm

Hence, length of the diagonal = a√2        

=25√2 cm

=25 x 1.414 cm

=35.35 cm

Answer 2

using hypotonous perpendicular method we can solve it as
$25 {}^{2} + 25 {}^{2} = x {}^{2} \\ 625 + 625 = x {}^{2} \\ 1250 = x {}^{2} \\ x = 35.35$
35.35 is the lenght of the diagonal
