The value of w is 5 units
Step-by-step explanation:
Let l be the length of the rectangle
and w be the width
Then
l = 2w - 1
Dividing both sides by 6
Hence
The value of w is 5 units

Given:
Center of a circle is at point C(-1,2).
AB is the diameter of the circle.
Coordinates of the point A are A(2,6).
To find:
The coordinates of point B.
Solution:
Let the coordinates of point B are (a,b).
If AB is the diameter of the circle, then A and B are end points of diameter of the circle and the center C is the midpoint of AB.
Point C = Midpoint of AB
On comparing both sides, we get
Similarly,
Therefore, the coordinates of point B are (-4,-2).
