The pad in the form of (not necessarily regular) octagon
is manufactured from a square. The side of the square is
\(4\, \mathrm{cm}\). An isosceles right
triangle of the hypotenuse \(1\, \mathrm{cm}\)
is removed from each corner of the square which results in the desired octagon. How
much of the material of the initial square goes to the waste?
\(12.5\, \%\)
\(10\, \%\)
\(15\, \%\)
\(20\, \%\)
