Question

If the centroid and two vertices of a triangle
are (4,-8),(-9,7), (1,4) then the area of the
triangle (in sq. units) is​

Answer 1

Answer:

Step-by-step explanation:

Let the third vertex be (x,y)

Centroid formula = (x1+x2+x3 / 3) , (y1+y2+y3 / 3)

Using the above formula we can find the third vertex= (20 , -35)

Now we use the area of the triangle formula

Area= 1/2*[x1*(y2-y3) + x2*(y3-y1) + x3(y1-y2)]

Substitute and solve

Area= 166.5 sq. Units
