well, it depends on WHAT polygon that you are talking about. For example, if the figure that you were talking about was a square, then the perimeter would be
sqrt20 = one side length
8sqrt5= perimeter of square
and so on and so forth...

How long is the perimeter of a square with an area of 25cm squared?
P = 20cm
A square has a perimeter of 20 cmWork out its area?
20cm/4sides = 5cm 5cm*5cm = 25cm^2
What is the area of a trapezoid if the perimeter is 32?
Unlike a square, knowing the perimeter of a trapezoid is not enough to be able to calculate its area. Think of a rectangle with a perimeter of 20cm. One possibility is that it has a length of 8cm and a width of 2cm. This would give and area of 16cm2. However the rectangle could have also had a length of 7cm and a width of 3cm as this would also give a perimeter of 20cm. However this rectangle now has an area of 21cm2. To be able to calculate the area of the trapezoid, you would need to know more about it than just its perimeter.
