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.
Two methods :_ 1) The sum of the interior angles of a regular polygon is 2n - 4 right angles. For a 14 sided polygon then (2 x 14) - 4 = 24 right angles = 24 x 90 = 2160° Therefore each interior angle = 2160 ÷ 14 = 154.29° (2dp) 2) The external angle of a 14 sided regular polygon = 360 ÷ 14 = 25.71° The interior angle = 180 - external angle = 180 - 25.71 = 154.29°
Area = pi*142

Area = 615.75 square feet.
Such a polygon is not possible.

It has 14 sides! The regular polygon with 14 sides is called a tetradecagon.
The area of a circle with a 14 cm radius is: 615.8 cm2
The area of a circle with the radius of 14 units is: 615.8 square units.
A circle with a radius of 14 feet has an area of 615.75 square feet.
The area of a circle with a radius of 14 is: 615.75 square units.
The area of a circle is 3.14 times the radius square.Accordingly the radius of the above mentioned circle is 14 meters.
