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

Mathematics

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.

A:
add up all the money he deposited
3.98+51.02+38.52+12.70=$106.22
and all the money withdrew:
-5.23-5.22-3.50-4.39=-18.34

b-
3.50, 3.98, 4.39, 5.22, 5.23, 12.7 38.52 51.02
just look at the digits from left to right the bigger they are the bigger the number is.if they were equal look at the next digit:
example:
3.50 and 12.7
there is a 1 in 12.7 tenth place but 3.50 doesn't even have a tenth place(or rather, it has a zero on it's tenth place) so 12.7 is bigger than 3.50

c-add all deposits and subtract all withdrawals:
106.22+98-18.34=185.88
