[tex]b[/tex] - the side of a square

[tex]a=b\sqrt2\\b=\dfrac{a}{\sqrt2}\\\\b=\dfrac{a\sqrt2}{2}[/tex]

Answer:

a√2 / 2.

Step-by-step explanation:

Using the Pythagoras Theorem;

a^2 = s^2 + s^2 where s is the length of each side of the square.

2s^2 = a^2

s^2 = a^2 / 2

s =  √(a^2 / 2)

= a / √2

= a√2 / 2 .
