PLEASE TELL ME AREA OF REGULAR HEPTAGON AND OCTAGON?ALSO TELL ME WHAT IS APOTHEM?
The apothem of a regular polygon is a line segment from the centre to the mid-point of one of its sides
Since the incircle touches all the sides of the polygon, apothem is the radius of the incircle of the polygon.
Apothem of a regular hexagon is shown in the figure below

The area of a regular polygon is given by :
For a regular heptagon, number of sides is 7
So perimeter = 7 * l ( l - length of each side)
Let apothem =a
Area=
For a regular octagon, number of sides is 8
So, perimeter = 8 l( l- length of each side)
Let apothem =a
Area=
