If the points `(2k, k),(k,2k)` and `(k, k)` with `k>0` enclosed a triangle of area 18 square units then the centroid of the triangle is equal to

If the points (2k, k), (k, 2k) and (k, k) with kgt0 enclose in a triangle of area 18 sq units, then the centroid of triangle is equal to

If (k,2),(2,4) and (3,2) are vertices of the triangle of area 4 square units then determine the value of k.

If (k,2) ,(2,4) and (3,2) are vertices of the triangle of area 4 square units then determine the value of k.

Let k be an integer such that the triangle with vertices (k, -3k), (5, k) and (-k, 2) has area 28 sq units. Then, the orthocentre of this triangle is at the point

Let k be an integer such that the triangle with vertices (k, -3k), (5, k) and (-k, 2) has area 28 sq units. Then, the orthocentre of this triangle is at the point

Let k be an integer such that the triangle with vertices (k ,-3k),(5, k) and (-k ,2) has area 28s qdot units. Then the orthocentre of this triangle is at the point : (1) (1,-3/4) (2) (2,1/2) (3) (2,-1/2) (4) (1,3/4)
