Calculating Area Red ÷ Area Square Exactly.


Let the single side length of the square be 2 units.


Therefore;


Area square is;


2 x 2


= 4 square units.


Calculating Red Area.


It will be;


½(area square with single side length 2 units) - Area triangle with base 2(2-√(3)) units and height 2 units - Area sector with radius 2 units and angle 30°.


= ½(4) - ½(2*2(2-√(3)) - (4π/12)


= 2 - 4 + 2√(3) - (π/3)


= ⅓(6-12+6√(3)-π)


= ⅓(6√(3)-6-π)


= (42√(3)-42-22)/21


= (42√(3)-64)/21 square units.


Therefore;


Area Red ÷ Area Square is;


((42√(3)-64)/21)÷4


= (42√(3)-64)/84


= (21√(3)-32)/42
