If the sides of a square is increased by 25%, then the area of the square will be increased by

A) 125%
B) 50%
C) 56.25%
D) 53.75%

Correct Answer:



C) 56.25%

Description for Correct answer:

Required increment

= \( \Large \left(2a+\frac{a^{2}}{100} \right)% \)

= \( \Large \left(2\times 25+\frac{(25)^{2}}{100} \right) \)

= \( \Large \left(50+\frac{625}{100} \right)% \)=56.25%
