Hexagon, heptagon, octagon, nonagon all have more sides than a pentagon
pentagon, hexagon. heptagon, octagon, nonagon ..... etc
Heptagon, octagon, nonagon, decagon, hendecagon, and dodecagon. There are many more.
Assuming same side length, the the heptagon with 7 sides will have a greater area than a hexagon with 6 sides. If the side lengths are not equal, then: If the side of the hexagon is approx 1.183 times that of the heptagon then the areas are the same. Thus when the side of the hexagon is less than ~1.183 times that of the heptagon it will have a smaller area; conversely, if the side of the hexagon is more than ~1.183 times that of the heptagon it will have a larger area.
