`" The area of the triangle OAB with vertices "O(0,0),A(x_(1),y_(1))" and "B(x_(2),y_(2))" is "ul(sq)" units "`

The area of the triangle OAB with vertices O(0,0),A(x_(1),y_(1))B(x_(2),y_(2)) is

Write the formula for the area of the triangle having its vertices at (x_(1),y_(1)),(x_(2),y_(2)) and (x_(3),y_(3))

If a, x_(1),x_(2) are in G.P with common ratio r and b, y_(1),y_(1) are in G.P with common ratio s where s-r=2 , then the area of the triangle with vertices (a,b),(x_(1),y_(1)),(x_(2),y_(2)) is

Area of the triangle formed by (x_(1),y_(1)),(x_(2),y_(2)),(3x_(2)-2x_(1),3y_(2)-2y_(1)) (in sq.units) is

STATEMENT-1 : The centroid of a tetrahedron with vertices (0, 0,0), (4, 0, 0), (0, -8, 0), (0, 0, 12)is (1, -2, 3). and STATEMENT-2 : The centroid of a triangle with vertices (x_(1), y_(1), z_(1)), (x_(2), y_(2), z_(2)) and (x_(3), y_(3), z_(3)) is ((x_(1)+x_(2)+x_(3))/3, (y_(1)+y_(2)+y_(3))/3, (z_(1)+z_(2)+z_(3))/3)

If the area of the triangle with vertices x,0,1,1 and 0,2 1, 4 sq units,then the value of x is :

If O is origin,A(x_(1),y_(1)) and B(x_(2),y_(2)) then the circumradius of Delta AOB is

" The area (in sq.units) of the triangle formed by the lines "x=0,y=0" and "3x+4y=12" is equal to "
