In measuring the sides of a rectangle, one side is taken 6% in excess and other 5% in deficit. Find the error percentage in the area calculated from these measurements.  Pick one.
A) 3.5%	B) 2.4%	C) 3%	D) 5%	E) 0.7%
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 106*95=10,070, which is 0.7% greater than the actual area.   Answer: 0.7%.
