    give some context about this problem, is it a school problem? maybe olimpics or something, idk. I think i need information about the quadrilateral, is it a trapezoid, or maybe a parallelogram. Does the problem comes with a graph?

    All i can think of is Brahmagupta's formula \[A=\sqrt{(s-a)(s-b)(s-c)(s-d)}\] where s=a+b+c+d, and a,b,c,d are the sides of the quadrilateral but i dont have any information about the quadrilateral being inscribed in a circle. So i'm sorry, i can't help you, keep bumping and maybe someone does it
