In measuring the sides of a rectangle, one side is taken 5% in excess, and the other 4% in deficit. Find the error percent in the area calculated from these measurements.  Choose the correct choice from the following answers:
A) 0.2%
B) 0.4%
C) 0.6%
D) 0.8%
E) 1%
Let x and y be the sides of the rectangle. Then, Correct area = xy.   Calculated area = (105/100)*x * (96/100)*y = (504/500 )(xy)   Error In measurement = (504/500)xy- xy= (4/500)xy   Error % = [(4/500)xy*(1/xy) *100] % = (4/5)=
