Q1: An error 2% in excess is made while measuring the side of a square. The percentage of error in the calculated area of the square is:

A 2%

B 2.02%

C 4%

D 4.04%

ANS:A - 2%

00 cm is read as 102 cm.  A1 = (100 x 100) cm2 and A2 (102 x 102) cm2. (A2 - A1) = [(102)2 - (100)2] = (102 + 100) x (102 - 100) = 404 cm2.

 Percentage error = 404 x 100 % = 4.04%
