Let $IJKLMN$ be a hexagon with side lengths $IJ = LM = 3,$ $JK = MN = 3,$ and $KL = NI = 3$. Also, all the interior angles of the hexagon are equal. Find the area of hexagon $IJKLMN$.
The first two sentences is just a complicated way of descibing a hexagon with a side length of 3. The area of a hexagon with a side length n is3√32n2
Therefore,
A=3√3262
=3√3236
3√3(18)
=54√3
