##8## squares along each side of the game board. There are total ##32+32=64## squares and as chessboard is a square it has ##sqrt64=8## squares along each […]
##(1+sqrt(2))/2## assuming the values are in degrees ##sin(45)=sin(pi/4)=sqrt(2)/2## ##cos(60)=cos(pi/3)=1/2## so ##sin(45)+cos(60)=sqrt(2)/2 + 1/2## ##=(1+sqrt(2))/2##
