Area = Length × Breadth =55.3 × 25 =1382.5 =14 × 102 Resultant should have 2 significant figures.

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

$14 \times 1 0^{2}$

$138 \times 1 0^{1}$

$1382$

$1382.5$

Area $=$ Length $\times$ Breadth
$= 55.3 \times 25$
$= 1382.5$
$= 14 \times 1 0^{2}$
Resultant should have $2$ significant figures.
