In measuring the sides of a rectangle, one side is taken 10% in excess and other 5% in deficit. Find the error percentage in the area calculated from these measurements.	Options
A) 3.5%	B) 2.4%	C) 3%	D) 4.5%	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 110*95=10,450, which is 4.5% greater than the actual area.   Answer: 4.5%.
