If vertices of a triangle are (1,k),(4,-3),(-9,7) and its area is 15 square units, find the value (s) of k.

The area of a triangle with vertices (-3,0),(3,0) and (0,k) is 9 sq. units. The value of 'k' will be

The vertices of a triangle are (1, 2), (h, -3) and (-4, k). Find the value of sqrt({(h+k)^(2)+(h+3k)^(2)}) . If the centroid of the triangle be at point (5, -1).

Two vertices of a triangle are (-1, 4) and (5, 2). If its centroid is (0, -3), find the third vertex.

If area of /_\ABC is 12 square units and vertices are A (x, 2), B (4, - 1) and C (- 3, 7), then find the value of x.

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)

The area of a triangle with vertices at (-4,-1), (1,2) and (4,-3) is:

The sides of a triangle are in the ratio 3:5:7 and its perimeter is 600 cm. Find the area of the triangle.
