Question

find the coordinates of centroid of a triangle ABC with A(7,4) B(4,8), C(11,7)​

Answer 1

A=(7,4)

B=(4,8)

C=(11,7)​

Centroid of a triangle is given by:- $(\frac{x_{1}+x_{2}+x_{3} } {3}\ ,\frac{y_{1}+y_{2}+y_{3}}{3})$

∴ x-coordinate--->(7+4+11)/3 = 22/3

  y-coordinate--->(4+8+7)/3 = 19/3

Thus the coordinates of centroid of the triangle is (22/3,19/3)
