We'll use the sine function to help compute the area. Make sure your calculator is in degree mode.


Area of parallelogram = (side1)*(side2)*sin(included angle)
Area of parallelogram = (4)*(9)*sin(40)
Area of parallelogram = 36*sin(40)
Area of parallelogram = 36*0.64278760968653
Area of parallelogram = 23.140353948715
Area of parallelogram = 23.1


Answer: 23.1 square cm
