Area Red Total in 1 d. p. Square unit is;
Area Square with side 2√(2) units - Area triangle with height 2√(2) units and base 1.1313708499 units + Area triangle with two side √(13) units and 3.28571428572 units, and angle atan(3/2)°
= (2√(2))² - 0.5*2√(2)*1.1313708499 + 0.5*√(13)*3.28571428572sin(atan(3/2))
= 8 - 1.6 + 4.92857142858
= 11.3285714286
≈ 11.3 square units.
