In a recatngle ABCD, the coordinates of A and B are (1, 2) and (3, 6) respectively and some diameter of the circumscribiling circle of ABCD has equation `2x-y+4=0`. Then the area of the rectangle is -

In a rectangle PQRS ,the coordinates of P and Q are (1,3) and (2,6) respectively and some diameter of the circumscribing circle of PQRS has the equation 3x-y+2=0. Then the area of the rectangle is

If 4y=x +7 is a diameter of the circumscribing circle of the rectangle ABCD and A(-3,4), B(5,4). then the area of the rectangle.

ABCD is a rectangular A circle circumscribing the rectangle. The coordinates of A and C are (-3, 4) and (5, 4) respectively. If (a, 0) is lying inside the circumscribe circle then the expected value of a will be -

ABCD is a parallelogram.If the coordinates of A,B,C are (2,3),(1,4) and (0,-2) respectively,find the coordinates of D.

ABCD is parallelogram.If the coordinates of A,B,C are (-2,-1),(3,0) and (1,-2) respectively,find the coordinates of D.

A foot of the normal from the point (4, 3) to a circle is (2, 1) and a diameter of the circle has the equation 2x -y -2 =0 . Then the equation of the circle is:

The sides of the rectangle ABCD are parallel to the axes. If the coordinates of A and C are (12, 3) and (7, 6) respectively, find the coordinates of D.

The foot of the normal from the point (1,2) to a circle is (3,4) and a diameter of the circle has the equation 2x+y+5=0 ,then the equation of the circle is

ABCD is a parallelogram. If the coordinates of A ,\ B ,\ C\ a r e\ (2,3),\ (1,4)a n d\ (0,-2) respectively, find the coordinates of D.
