In a dimensional coodinate a system P, Q and R are image of a point A(a, b, c) in the XY they YZ and the ZX planes respectively. If G is the centroid of triangle PQR then area of Triangle AOG is (O is origin).

In a three dimensional co-odinate , P, Q and R are images of a point A(a, b, c) in the xy, yz and zx planes, respectively. If G is the centroid of triangle PQR, then area of triangle AOG is (O is origin)

ABC is a triangle.The coordinates of whose vertices are (-2,4),(10,-2) and (-2,-8).G is the centroid of triangle ABC, then area of the triangle GBC is equal to 26(b)36 (c) 24 (d) 39

If Delta_(1) is the area of the triangle formed by the centroid and two vertices of a triangle Delta_(2) is the area of the triangle formed by the mid- point of the sides of the same triangle, then Delta_(1):Delta_(2) =

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

The centroid of a triangle lies at the origin and the coordinates of its two vertices are (-8, 0) and (9, 11), the area of the triangle in sq. units is
