The area of a hexagon with a perimeter of 12 units is about 10.4 units2
A regular hexagon that has a perimeter of 18 units of measurement
Hexagon means six sides. Regular means six EQUAL sides. If one side is 9, then the whole thing has a perimeter of 9 x 6 = 54 units. Area would be more complicated. ^_^
Perimeter = 6*13 = 78 units

A regular hexagon that has a perimeter of 18 units of measurement
7.5 units of length.
Hexagon means six sides. Regular means six EQUAL sides. If one side is 9, then the whole thing has a perimeter of 9 x 6 = 54 units. Area would be more complicated. ^_^
The area of a regular hexagon with side lengths of 10 units is about 259.8 units2
Since a hexagon has six sides, a hexagon with sides of 14.7 inches will have a perimeter of 14.7 x 6 = 88.2. Don't forget to specify units of measure in your answer.
There are infinitely many possible answers. Even considering only regular polygons, a triangle with sides of 8 units, a square with sides of 6, a pentagon with 4.8, hexagon with 4, etc. An n-sided polygon with sides of 24/n units will have a perimeter of 24 units. And then there are all the irregular polygons - far more numerous than regular ones.
12Infinitely many all different:As it is only the area that matters, the perimeter can be any shape:An equilateral triangle (with sides approx 3.398 units)A square (with sides approx 2.236 units)A regular pentagon (with sides approx 1.705 units)A regular hexagon (with sides approx 1.387 units)A regular heptagonA regular octagonA regular nonagonA regular decagonA regular hendecagon (11 sided polygon)A regular dodecagon (12 sided polygon)A regular triskaidecagon (13 sided polygon)A regular 14 sided polygonA regular 15 sided polygonA regular 16 sided polygon...A circle (with radius approx 1.262 units)And there are also the non-regular shapes, eg an L shaped hexagon, a kite, a parallelogram which can have an area of 5 square units.
If the sides are of length 4 units then the perimeter is 8*4 = 32 units. Its area is then 77.255 square units.
