The percentage increase in the area of a rectangle, if each of its sides is increased by 20% is?  Options:
A) 44%  B) 45%  C) 50%  D) 55%  E) 60%
Let original length = x metres and original breadth = y metres.   Original area = (xy) m2.   New length = 120	x	m	= 6	x	m.   100	5   New breadth = 120	y	m	= 6	y	m.   100	5   New Area = 6	x x	6	y	m2	= 36	xy	m2.   5	5	25   The difference between the original area = xy and new-area 36/25 xy is   = (36/25)xy - xy   = xy(36/25 - 1)   = xy(11/25) or (11/25)xy   Increase % = 11	xy x	1	x 100	%	= 44%.   44%)
