A perimeter is a 1-dimensional measure while an area is 2-dimensional. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. For any given perimeter there are infinitely many possible areas and conversely.

Perimeter = 4*Side so that Side = Perimeter/4 Area of a rhombus = Side * Altitude so Altitude = Area/Side = Area/(Perimeter/4) = 4*Area/Perimeter
It must be a perimeter. An area measurement would a square measurement like 56cm². ■
Even if you knew how many sides the polygon has, you stillcould not calculate its perimeter with that much information.Examples:-- An equilateral triangle with area of 20 has perimeter of 20.3885 .-- A square with area of 20 has perimeter of 17.889(rounded).-- A rectangle with area of 20 can have any perimeter more than 17.889 .4 by 5 . . . . area = 20, perimeter = 182 by 10 . . . area = 20, perimeter = 241 by 20 . . . area = 20, perimeter = 42..etc.
Because area is a function of perimeter.
zero is the least area and the max area, is of a circle of perimeter 40 .....
