The error in the measurement of the length and the breadth of a rectangular table is \(1 \%\). If the length and breadth of the table are \(1 \mathrm{~m}\) and \(50 \mathrm{~cm}\) respectively, then the area of the table including error is
- A \((0.5 \pm 0.1) \mathrm{m}^2\)
- B \((0.5 \pm 0.01) \mathrm{m}^2\)
- C \((5000 \pm 10) \mathrm{cm}^2\)
- D \((5000 \pm 1) \mathrm{cm}^2\)
Answer & Solution
Correct Answer
(B) \((0.5 \pm 0.01) \mathrm{m}^2\)
Step-by-step Solution
Detailed explanation
According to the question, Length of the rectangle, \(l=1 \mathrm{~m}\) and breadth, \(b=50 \mathrm{~cm}=0.5 \mathrm{~m}\) \(\therefore\) Area of rectangle, \(A=l \times b\)…
