Total Area $=A_1+A_2+\ldots \ldots \ldots A_7$
$ =A+A+\ldots \ldots \ldots \ldots 7 \text { times }$
$ =37.03 m^2$
Addition of $7$ terms all having $2$ terms beyound decimal,
so final answer must have $2$ terms beyond decimal $($as per rules of significant digits$)$

- 1A person measures the depth of a well by measuring the time interval between dropping a stone and receiving the sound of impact with the bottom of the well. The error in his measurement of time is $\delta \mathrm{T}=0.01$ seconds and he measures the depth of the well to be $\mathrm{L}=20$ meters. Take the acceleration due to gravity $\mathrm{g}=10 \mathrm{~ms}^{-2}$ and the velocity of sound is $300 \mathrm{~ms}^{-1}$. Then the fractional error in the measurement, $\delta \mathrm{L} / \mathrm{L}$, is closest toView Solution
