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 error percent in the area calculated from these measurements.	Choose the correct choice from the following answers.
A) 0.8%	B) 0.2%	C) 0.4%	D) 0.9%	E) 0.6%
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=

<output>4/5 = around 0.8</output>
0.8%.   0.8%nswer is 0.8%
