Question 1111171
If I divide the hexagon into 6 equalateral
triangles, their sides will be {{{ 30/2 = 15 }}} m
-------------------
Next find the area of one of the equilateral triangles.
{{{ A = (1/2)*15*(15/2)*sqrt(3) }}}
{{{ A = (1/4)*15^2*sqrt(3)  }}}
----------------------------
To find the area of the hexagon:
{{{ 6A = (3/2)*15^2 *sqrt(3) }}} m
I went over it twice, so I think it's right
