Area orange exactly in its decimal form is;
Half area square with side 12 units - Area triangle with height 12 units and base 12tan15 units - Area triangle with two side 5.56921938165 units and 5.379452833 units, and angle 45°
= ½(12²) - ½(12*12tan15) - ½(5.56921938165*5.379452833)sin45
= 72 - 19.292341855 - 10.5922308261
= 42.115427319 square units.
