The figure can be redraw as,
The EF is equal to radius of the circle, so EF = 4.3 m.
HE is perpendicular bisector of FG. So,
[tex]\begin{gathered} FH=\frac{6.6}{2} \\ =3.3 \end{gathered}[/tex]Determine the length of EH by using pythagoras theorem.
[tex]\begin{gathered} (EH)^2=(EF)^2-(FH)^2 \\ =(4.3)^2-(3.3)^2 \\ =14.49-10.89 \\ EH=\sqrt{3.6} \\ =1.897 \\ \approx1.90 \end{gathered}[/tex]Thus length of side EH is 1.90 meters.
