Find the area of the triangle, whose vertices are (2,1), (4,5) and (6, – InterviewSolution

1.	Find the area of the triangle, whose vertices are (2,1), (4,5) and (6,3).
Answer» Area of triangle `=1/2[x_(x)(y_(2)-y_(3))+x_(2)(y_(3)-y_(1))+x_(3)(y_(1)-y_(2))]` `=1/2[2(5-3)+4(3-1)+6(1-5)]=1/2(4+8-24)= -6` But the area of triangle connot be negative `therefore" "` Area of triangle = 6 square units
