<u>Given</u>:
The side length of a regular octagon is 11.7 cm
The apothem is 14.1 cm
We need to determine the area of the regular octagon.
<u>Perimeter of the regular octagon:</u>
The perimeter of the regular octagon is given by
Thus, the perimeter of the regular octagon is 93.6 cm
<u>Area of the regular octagon:</u>
The area of the regular octagon is given by
Substituting the values, we get;
Thus, the area of the regular octagon is 659.88 cm²
area = length * width
so length = area / width
length = 5 4/5 / 2 1/4
= 29/5 / 9/4
= 29/5 * 4/9
= 116 / 45
2.58 m to the nearest hundredth. As a fraction it is 2 26/45 m.
