If each side of a square is increased by 6%, find the percentage change in its area?  Choose the correct choice from the following answers.
A) 10.68%  B) 8.72%  C) 9.28%  D) 12.36%  E) 11.91%
let each side of the square be a , then area = a x a   New side = 106a / 100 = 53a /50   New area =(53a x 53a) / (50 x 50) = (2809a²/2500)   increased area== (2809a²/2500) - a²   Increase %= [(309a²/2500 ) x (1/a² ) x 100]% = 12.36%   answer :12.36%
