# If the length of the side of a square is doubled, then its area becomes

 A) 2 times B) 16 times C) 4 times D) 12 times

 C) 4 times

Description for Correct answer:
Let 'a' be the side of the square.

area = $$\Large a^{2}$$ sq. cm.

It is length is doubled, then the side = 2a

area = $$\Large \left(2a^{2}\right) = 4 a^{2}$$

The area becomes 4 times of that given square.
