Question: caculate the area which is defined by the intersections of two parabola

I am confused with this question. I have parabola1 which is 3*x^2-22x+7, and parabola2 which is -5/9*x^2+58/9*x-161/9. the area of par1 is −148.1481481, the area of par2 is −1.280000000.

How can I Calculate the area A3 which is defined by the intersections
of Par1 and Par2.
and Plot Par1 and Par2 with the area A3 “highlighted

thanks
