Answer:
The area of the octagon is 505.76
Explanation:
In this question, we are tasked with calculating the area of as regular octagon given the lengthy of its apothem ans its perimeter
Mathematically, the area of a regular octagon with an apothem can be calculated as follows
Area = 1/2 × apothem × perimeter
From the question, we can identify the length of the apothem as 11.6 inches and the perimeter of the octagon as 87.2 inches
Now, we plug these values
Area = 1/2 × 11.6 × 87.2 = 505.76
