State whether the following statements are true (T) or false (F):
(v) If the length of a rectangle is twice its breadth, then its area is a constant.
Here, the length and the breadth of the rectangle are not fixed. Their value depends on each other and the area of a rectangle is lengthbreadth so the value of the area depends on the value of length and the breadth. So, the value of the area is not constant.
