In measuring the sides of a rectangle, one side is taken 16% in excess and other 5% in deficit. Find the error percentage in the area calculated from these measurements.	Select:
A) 3.5%
B) 2.4%
C) 10.2%
D) 5%
E) 2.6%
Say both sides of the rectangle are equal to 100 (so consider that we have a square). In this case the area is 100*100=10,000.   Now, the area obtained with wrong measurements would be 116*95=11,020, which is 10.2% greater than the actual area.   Answer: 10.2%.
