a line OP25 is drawn and pointz p1,p2,p3....p24 are marked on line.Squares are constructed such that op1,p1p2,p2p3..........p24p25 are diagonals of the respective squares. the area of squares considered in the same order are 2,4,8,16..... the 25th square is named P24 B P25 D.The distance OD is approximatly

1) 2^12*6^.5*(2^.5 -1)
2) 2^12*6^.5*(2^.5 +1)
3) 2^10*(2^.5 +1)
4) 2^10*(2^.5 -1)
