Area of the triangle is 14.4914.49 sq.unit.

Explanation:

Angle between Sides A and CAandC is

/_b= (5pi)/24=(5*180)/24=37.5^0b=5π24=518024=37.50

Angle between Sides B and CBandC is

/_a= (3pi)/8=(3*180)/8=67.5^0 :.

Angle between Sides A and B is

/_c= 180-(37.5+67.5)=75^0

Now we know sides A=6 , B=5 and their included angle

/_c = 75^0. Area of the triangle is A_t=(A*B*sinc)/2

:.A_t=(6*5*sin75)/2 ~~ 14.49 sq.unit

Area of the triangle is 14.49 sq.unit [Ans]
