PhysicsNEET 2022Significant figures and errors in measurement

Units and Measurements

The area of a rectangular field (in $m^{2}$ ) of length 55.3 m and breadth 25 m, after rounding off the value to the correct significant digits, is:

A. $14 \times 1 0^{2}$ ✓
B. $138 \times 1 0^{1}$
C.1382
D.1382.5

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
