For the original 10m of windows the heat loss is 70w/degree C 2. If I double glazed those windows the heat loss is 35w/degree C a reduction of 35w 3. If I reduced the window size by 40% (to 6m) the heat loss is now 45w/degree C a reduction of 25w (that means the window reduction has resulted in an improvement that is 70% of the benefit of double glazing but at no cost) 4. If I reduced the window size by 40% and then double glazed the heat loss would be 23w/degree a reduction of 47w ( that means the the window reduction plus double glazing has reduced the heat loss by about 30% more than double glazing alone) Your last line where you suggest a window size of 3.6 is a further reduction of 40% of the window area which had already been reduced.
