If that was an answer to my post, there exists such a formula and it is called Heron's Formula. It is used to find the area of a triangle only by using the sides. What I did is clear and correct. Integral provided just another way to find the area.stupidkid said:it is definately possible and pretty easy but there is no such formula or it maybe be complicated.

actually my friend asked me this question, and i said to him
it is not possible because the trapezium is not unique.
