Question

A square, whose side is 4 metres, has its corner cut away so as to form an octagon with all its sides equal. Find the length of each side of the octagon in metres. EXPLAIN IT PROPERLY

Answer 1

see diagram.

a = 4 m 2 x + x √2 = a                so  x = a / (2+ √2)x = 4 - 2 * √ 2Side of octagon :  x √2 =  4 (√2 - 1) = 1.64  m    approx.

Answer 2

Answer:

4 (√2 - 1)
