Find the area of a regular nonagon with a side length of 7 and an apothem of 5

The formula for finding the area of a regular polygon is 1/2 (apothem) (perimeter).

Well, since this is a nonagon (9 sides) and each side has a length of 7, so 7 times 9 equals 63 (perimeter of the shape).

Now, we have all the information we need to plug into our formula:

1/2 (5) (63). I already set up the equation for you, so you just need to evaluate it.
