It has 1 more side
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.
It is a pentagon which has 5 sides
A heptagon has 7 sides and a pentagon has 5 sides so a heptagon has 2 more sides than a pentagon
A decagon has 10 sides A heptagon has 7 sides Therefore a decagon has 10 - 7 = 3 more sides than a heptagon.
hexagon, heptagon, octagon, nonagon, decagon, undecagon, dodecagon .... etc
One more side
hexagon, heptagon
Heptagon, octagon, nonagon, decagon, hendecagon, and dodecagon. There are many more.

How about: pentagon, hexagon, heptagon, octagon .... etc
Hexagon, heptagon, octagon, nonagon all have more sides than a pentagon
It is a pentagon which has 5 sides
Pentagon, hexagon, heptagon, octagon ... etc
An octagon has two more sides than a hexagon
There are many. To name a few: heptagon (7), octagon (8), nonagon (9), and decagon (10).
A heptagon has 7 sides and a pentagon has 5 sides so a heptagon has 2 more sides than a pentagon
A decagon has 10 sides A heptagon has 7 sides Therefore a decagon has 10 - 7 = 3 more sides than a heptagon.
