A = (1/2)Pa
A being the area, P being the perimeter of the regular polygon, and the apothem length being a.
Area of regular polygon: 0.5*apothem*perimeter
The formula used to find the area of any regular polygon is A = 1/2 a P where the lower case a stands for the length of the apothem and the uppercase P stands for the perimeter of the polygon.
If it is a regular polygon--meaning that all the sides are congruent and all the angles are congruent, then the formula for area of the polygon is A=1/2 ap Here a represents the apothem, which is the distance from the center of the polygon to the midpoint of one side. p represents the perimeter of the polygon found by multiplying one side length by the number of sides. If you only know one variable such as side length, you can find the perimeter and you can find the apothem using trigonomety.

Yes, for the perimeter of a polygon, you add up all the sides.
Area of regular polygon: 0.5*apothem*perimeter
Perimeter = 2*Area/Apothem.
The formula used to find the area of any regular polygon is A = 1/2 a P where the lower case a stands for the length of the apothem and the uppercase P stands for the perimeter of the polygon.
The formula for finding the area (A) of a regular polygon when its perimeter (p) and apothem (a) are known is: A=(pa)/2 Therefore, when the figures are put into the formula it becomes: A=(20 x 3)/2 A=60/2 A=30 square feet
Find the apothem of a regular polygon with an area of 625 m2 and a perimeter of 100 m.
Assuming that you are talking about a regular hexagon, the equation is (1/2)ap, a being the apothem and pbeing the perimeter. You can also use that equation for any other regular polygon.
The apothem is 12.5 metres.
add all the sides ???
Finding the perimeter of a polygon is finding how far it is in total along all the edges of the polygon; whereas finding the area of a polygon is finding how much space the polygon covers. The perimeter of a polygon forms the boundary around the area of the polygon.
Such a polygon is not possible.
The formula to find the area of a dodecagon (12-sided polygon) is (apothem x perimeter)/2.
