Question 84676
Area of square section of window={{{s^2}}}

Area of semicircle section of the window={{{pi*s^2/8}}}
Note: radius of semicircle portion is {{{(s/2)}}}

Total area of window(At) equals area of square section plus area of semicircle section or:

{{{At=s^2+pi*s^2/8}}} and this equals:

{{{At=s^2+(3.14/8)*s^2}}} which equals:

{{{At=s^2+0.3925*s^2}}} and we have

{{{At=1.3925*s^2}}}
