Area Calculation

Given the following coordinate values, compute the area in square feet.

N$1=1000\mathrm{.}0000$ E$1=1000\mathrm{.}0000$

N$2=815\mathrm{.}1304$ E$2=750\mathrm{.}9578$

N$3=1312\mathrm{.}7831$ E$3=910\mathrm{.}7613$

N$1=1000\mathrm{.}0000$ E$1=1000\mathrm{.}0000$

$$

Round final answer to nearest "whole foot"

example answer $29253$
