Question

Find the co-ordinates of the centroid of the triangle whose vertices are (3, -5), (4, 3) and (11, -4).

Answer 1

Here $x_1=3,x_2=4\&x_3=11$
And $y_1=-5,y_2=3\&y_3=-4$

Co-ordinates of centroid:
$(x,y)=(\frac{x_1+x_2+x_3}{3},\frac{y_1+y_2+y_3}{3})=(\frac{3+4+11}{3},\frac{-5+3-4}{3})=(\frac{18}{3},\frac{-6}{3})$

$\therefore$ Centriod of the triangle is (6 , -2).
