[" 13.If the vertices of the "Delta ABC" are "(3,8),],[(-4,2)" and "(5,-1)" then the area of "Delta ABC" is "]

Find the area of the triangle with vertices (3,8),(-4,2) and (5,1) .

The vertices of a Delta ABC are A (-5,-1), B (3,-5) , C (5,2). Show that the area of the Delta ABC is four times the area of the triangle formed by joining the mid-points of the sides of the triangle ABC.

If the vertices of Delta ABC are A(5,-1) , B (-3,-2), C(-1,8) find the length of median through A.

If the coordinates of the midpoints of the sides of Delta ABC are (1,1), (2,-3) and (3,4) , find the coordinates of the vertices of Delta ABC

Let the lengths of the altitudes drawn from the vertices of Delta ABC to the opposite sides are 2, 2 and 3. If the area of Delta ABC " is " Delta , then find the area of triangle
