A is the answer since if you graph it, it has those points, or you may just simply plug in the x points that are given and see if they equal the y number
Answer: 331.5 inches²
Step-by-step explanation:
To solve for the area of a regular octagon, we can use the formula that is shown below:
Area = 1/2 × apothem × perimeter
In this problem, we have been given the following values:
Apothem = 10 inches
Perimeter = 66.3 inches
To solve for the area,
Area = 1/2 × apothem × perimeter
Area = 1/2 × 10 × 66.3
Area = 331.5 inches²
