Multiple of total no of sides and length of each side.
The formula is:Perimeter = (length of one side) x (number of sides)
The general formula isPerimeter = (sum of the lengths of all sides)In the special case of a regular polygon,Perimeter = (length of one side) x (number of sides)
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
The formula for finding the area ( A ) of a regular polygon with an apothem ( a ) and the number of sides ( n ) is given by: [ A = \frac{1}{2} \times Perimeter \times Apothem = \frac{1}{2} \times (n \times s) \times a ] where ( s ) is the length of one side. Alternatively, it can also be expressed as: [ A = \frac{1}{2} \times P \times a ] where ( P ) is the perimeter of the polygon.
There can be no such formula in general. A formula will exist if the area is a regular polygon (or a circle).
Area of regular polygon: 0.5*apothem*perimeter
The formula is:Perimeter = (length of one side) x (number of sides)
A = (1/2)Pa A being the area, P being the perimeter of the regular polygon, and the apothem length being a.

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
The formula for finding the area ( A ) of a regular polygon with an apothem ( a ) and the number of sides ( n ) is given by: [ A = \frac{1}{2} \times Perimeter \times Apothem = \frac{1}{2} \times (n \times s) \times a ] where ( s ) is the length of one side. Alternatively, it can also be expressed as: [ A = \frac{1}{2} \times P \times a ] where ( P ) is the perimeter of the polygon.
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 side of the Polygon's measurements multiplied by 5.
There can be no such formula in general. A formula will exist if the area is a regular polygon (or a circle).
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 perimeter is the sum of the sides of a polygon. So, to find the perimeter of a pentagon, you need only to add up the 5 side lengths. In the event the pentagon is regular (all equal sides and angles) then you can multiply the measure of the side by 5 to get the perimeter.
