need help finishing program!

Question

i have the following program to figure the largest area of a triangle give a set of points. i have the class written to perform the needed mathematics but i am having some trouble getting it to work. can anyone help me!??? thank you To compute the area of a triangle use the formula: area = radical (s(s-a)(s-b)(s-c)) s - (a+b+c)/2 where and a, b, and c are the three sides of the triangle. To calculate the length of the sides you can use the distance formula: radical (x1-x2)^2+(y1+y2)^2 x1,x2 is one point y1,y2 is the second point where are the coordinates of one point and is the coodinates of the second point.
