Answer:

What is the formula for the area and perimeter of a septagon ?

The area (A) of a seven sided septagon can be found from any of the following relations which are applicable to all regular convex polygons:

A = (1/2) n s a,

A = (1/2) p a,

A = (1/4) n s^2 cot (pi/n),

A = n a^2 tan (pi/n),

A = (1/2) n R^2 sin (2 pi/n), where

n = number of sides ,

s = side of the septagon,

p = perimeter of the septagon,

a = apothem or the altitude of the isosceles triangle, there will be n isosceles triangles in n-sided polygon,

R = circumradius of the polygon,

pi = (22/7).

Answer:

\huge\mathfrak\pink{answer = 84 cm}

Step-by-step explanation:

Given polygon is a septagon

the Length of the side is m cm

Perimeter of a septagon

=7×length of the side

=>P=7m units

The length of the side =12 cm

Perimeter of the regular septagon=7×12=84cm
