    Area = ( 2 + 2√2 )*(x^2) where x is the side length

    in the regular octagon.there will be 8 equilateral triangle hence let the side is x. then area of octagon=8*area of one equilateral triangle =\[8\times \sqrt{3}\div 4 (x ^{2})\]..find x.

    Are you sure they are equilateral? I think in a hexagon they are equil. not octagon

    tan67.5=x let |dw:1334306229613:dw| x=root2+1 is only possible because 67.5 is in first quadrant and in first quadrant tan ins positive.hence neglect negative value(1-root2)
