From each corner of a square with an edge of 4 cm, a 1 cm segment was chopped off from each side containing a vertex. What is the perimeter and the area of the octagon thus created?
1
\(4{\rm{}} + {\rm{}}4\sqrt 2 {\rm{cm}};14{\rm{c}}{{\rm{m}}^2}\)
2
\(\left( {8{\rm{}} + {\rm{}}4\sqrt 2 } \right){\rm{cm}};14{\rm{c}}{{\rm{m}}^2}\)
3
16 cm, 12 cm2
4
\(4\sqrt 2 {\rm{cm}};14{\rm{c}}{{\rm{m}}^2}\)
