The cellar

Mr Novák has a cellar and a cellar window in the chalet has 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 what the total length of the bars he has to buy.

Correct result:

x =  0.4243 m
y =  1.6971 m


x=2 0.6/2=0.4243 m
y=4 2 0.6/2=1.6971 m
