Steps

How many steps do you save if you go square estate for diagonal (crosswise) rather than circumvent the two sides of its perimeter with 458 steps?

Correct answer:

x =  134.1

Step-by-step explanation:

$$\begin{gathered} n=458 \\ a=n/2=458/2=229 \\ {d}^2=a^2+a^2 \\ {d}^2=2a^2 \\ d=\sqrt{2}\cdot a=\sqrt{2}\cdot 229=229\sqrt{2}\doteq 323.8549 \\ x=n-d=458-323.8549=134.1 \end{gathered}$$
