The area of a rectangular field (in ) of length and breadth after rounding off the value of correct significant digits is:
1382
1382.5
Area length breadth
As, Answer of multiplication is rounded off to the same number of significant figure as present in least precise term. Here, 25 has least significant figure and it is 2 so, Answer will also have 2 SF.
Therefore, correct option is (c) i.e.
The errors in the measurement which arise due to unpredictable fluctuations in temperature and voltage supply are
Instrumental errors
Personal errors
Least count errors
Random errors
Random errors is also called chance error. It occurs due to parameter which are beyound the control of experimeter.
