okay so the question i have to answer is "write a maple function that computes the area of a triangle in the plane from the coordinates of the vertices" ive gotten this far Lookup "Shoelace formula" in Wikipedia. This will give the area of any polygon as long as the vertices are given in order (clockwise or counterclockwise).Area:= proc(P::list([realcons,realcons]))local k, n:= nops(P); abs(add(P[k,1]*P[k+1,2] - P[k+1,1]*P[k][2], k= 1..n-1) + P[n,1]*P[1,2] - P[1,1]*P[n,2])/2end proc:Area([[0,0], [10,0], [10,10]]);AreaOfTriangle:= proc(P::list([realcons,realcons]))uses G= geometry;local A,B,C,ABC; G:-area(G:-triangle(ABC, [G:-point(A, P[1][]), G:-point(B, P[2][]), G:-point(C, P[3][])]))end proc: AreaOfTriangle([[0,0], [10,0], [10,10]]);
