In Exercises 17 to 30, use the formula
In a regular octagon, the measure of each apothem is 4 cm, and each side measures exactly
To find:
The approximate area of a regular octagon.
1) The perimeter of a regular polygon is given by P = ns, where n is the number of sides and s is the length of any side.
2) The area of a regular octagon with apothem a and perimeter P is given by
Calculation:
It is given that the length of the apothem and side of a regular octagon are respectively 4 and
The total number of sides in a regular octagon is 8.
Use the formula for the perimeter of regular polygon, i.e., perimeter = ns
Substitute n = 8 and s =
P = (8)
=
