The "perimeter" of a circle is usually referred to as the circle's "circumference", i.e. the distance around it.
The circumference of a circle is [ 2 pi R ], where 'R' is the distance from the center of the circle to its curve.
If the circumference of a circle is 12, then 12 = [ 2 pi R ]. R = [ 12 / 2 pi ] = [ 6/pi ].
The area of a circle is [ pi R2 ].
If R = 6/pi, then the area is [ pi R2 ] = [ pi x (6/pi)2 ] = [ pi x 36 / pi2 ] = ( 36/pi ) = 11.459 square centimeters (rounded).

A shape with the same area and perimeter?
As a perimeter is a measure of length and has different units to those measuring an area then it is the numerical value that is the same. CIRCLE : area = perimeter occurs when πr2 = 2πr = : r = 2 SQUARE : area = perimeter when d2 = 4d : d = 4, where d is the length of a side.

How do you get the perimeter of a given area?
The perimeter of an area is the length around the outside. For simple shapes such as a square or a circle, the answer is not difficult to calculate. For a square, (length x breadth) = the area. For a circle, pi times the diameter, or roughly, 22/7 x the diameter = the area. For a geographic area, such as say the perimeter of Florida, this is easiest to determine by actually measuring around Florida's border on a map with a small rolling wheel, that converts the distance it travelled into length.
