Ans: B
Note that the maximum absolute error of the measurement
Note that the maximum absolute error of the measurement
$\begin{array}{cl}
= & \dfrac{1}{2} \times 1 \\
= & 0.5 \text{ cm}
\end{array}$
Hence, the least possible value of length
$\begin{array}{cl}
= & 12 – 0.5 \\
= & 11.5 \text{ cm}
\end{array}$
and the least possible value of breath
$\begin{array}{cl}
= & 10 – 0.5 \\
= & 9.5 \text{ cm}
\end{array}$
Therefore, the least possible area of the rectangle
$\begin{array}{cl}
= & 11.5 \times 9.5 \\
= &109.25 \text{ cm}^2
\end{array}$
