Area R ÷ Area Square exactly in its simplest decimal form is;
Area R is;
½(5x7.5) - ½(√(81.25)x√(65.25))sin(tan–¹(5/7.5) - tan–¹(3/7.5)) - ½((4.5)²xtan(tan–(3/7.5)) - ½(9sin(tan–¹(5/7.5))xsin(tan–(7.5/3))÷sin(180-(tan–¹(5.7.5))-(tan–¹(7.5/3))))
= 18.75 - 7.5 - 4.05 - 2.36842105263
= 4.83157894737 square unit.
Area square is;
3² = 9 square unit.
Therefore;
Area R ÷ Area Square exactly in its simplest decimal form is;
4.83157894737 ÷ 9
= 0.53684210526
