The cellar

Mr. Novák has a cellar, and the cellar window in the chalet is a 0.6-meter square window. The window wishes to place an X-shaped grid in a square. He uses iron welded bars. Calculate the lengths of individual bars and the total length of the bars he has to buy.

Final Answer:

x =  0.4243 m
y =  1.6971 m

Step-by-step explanation:

$$\begin{gathered} a=0.6\text{m} \\ x=\sqrt{2}\cdot a/2=\sqrt{2}\cdot 0.6/2=0.4243\text{m} \end{gathered}$$

$y=4\cdot x=4\cdot 0.4243=1.6971\text{m}$
