If each side of a square is increased by 25%, find the percentage change in its area.	Choose the correct choice from the following options
A) 26.25%	B) 36.25%	C) 46.25%	D) 56.25%	E) 66.25%
Let each side of the square be a. Then, area = a2.   New side =(125a/100) =(5a/4). New area = (5a/4) 2=(25a2)/16.   Increase in area = ((25 a2)/16)-a2=(9a2)/16.   Increase% = [((9a2)/16)*(1/a2)*100] % = 56.25%.   Option 56.25%
<result>D</result>
