there is a square with side ‘ a ’ and one octagon is inscribed in it . what will be perimeter of octagon .
well if it ' s a regular octagon then it actually trisects each side of the square in which 1 / 3 of the lenght of the side of the square is the length of one side of the octagon . if any one has a doubt he can draw the figure and see it going this way lenght of a side of a octagon is a / 3 and thus perimeter would be 8 a / 3 . answer : a
multiply(multiply(const_2, const_4), inverse(const_3))
