Guide to land area calculation with UTM coordinates using the NOS (Nearest Segment Offset) method. Compute areas interactively with the coordinates area calculator or length-based plots with the land area calculator.
\[
\begin{aligned}
5-A & =\sqrt{(41.19)^{2}-(32.83)^{2}} \\
& =24.87 \text{ Metres}
\end{aligned}
\]
\[
\begin{aligned}
2-B & =\sqrt{(32.49)^{2}-(23.73)^{2}} \\
& =22.19 \text{ Metres}
\end{aligned}
\]
From Trapezium 1-2-4-5,
\[
\begin{aligned}
\text{Area} & =\frac{1}{2} *(1-4) *[(5-A)+(2-B)] \\
& =\frac{1}{2} * 56.14 *[24.87+22.19] \\
& =1320.97 \text{ Sq.metres}
\end{aligned}
\]
