[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 .
