Area yellow is;
Area triangle with two side 8√(2) cm and 2 cm, and angle 45° - Area triangle with height (20/3) cm and base ⅓(20tan(45-2atan(⅓))) cm
= ½*2*8√(2)sin45 - ½*(20/3)*⅓(20tan(45-2atan(⅓)))
= 8 - (200tan(45-2atan(⅓)))/9
= (72 - 200tan(45-2atan(⅓)))/9 cm²
= (2666664 - 1058200)/333333 cm²
= 1608464/333333 cm²
= (1608464÷5291)/(333333÷5291)
= 304/63 cm²
= 4.8253968254 cm²
