The point A is on the Y-axis at a distance of 7.5 units from the origin.
∴ The coordinates are (0,7.5).
The point B is at a distance of 4 units from Y-axis and 5 units from X-axis.
∴ The coordinates of B are (4,5).
The point C is at a distance of 7.5 units from Y-axis and 2.5 units from X-axis.
∴ The coordinates of C are (7.5,2.5).
The point D lies on X-axis at a distance of 11 units from the origin.
∴ The coordinates of D are (11,0).
The point E is at a distance of 14.5 units from Y-axis and 6.5 units from X-axis.
∴ The coordinates of C are (14.5,6.5).
The point F is at a distance of 18 units from Y-axis and 9.5 units from X-axis.
∴ The coordinates of C are (18,9.5).
