Q46 of 106 Page 310

State whether the statements are true (T) or false (F).

Length of a side of a square and its area vary directly with each other.

False

Length of a side of a square and its area does not vary directly with each other, e.g. Let a be length of each side of a square.


So, area of the square = side2 = a2


So, if we increase the length of the side of a square, then their area increases but not directly.
