Perminter= P
Area= A
How to calculate the P: the p of this shape is pretty much easy to solve. Finding a P of a shape, you need to add all the sides up. So you just need to add 9+6+2+5+5+5+2+6. Remeber to double check that you got all the sides. Anothor equation you can do is (6x2) + (5x3)+(2x2)+9. Just pick a equation to do and you get the answer
how to caculate the A: Caucalating the A of this shape is actually a little hard. There is two ways to solve this but the second way to me is kinda hard. The first way is two divide this shape into rectangles and squares. So I dived it like this ( look at the image below). To calculate the area of a rectangle is to mutiply lengh by width. So first I will need to multiply 9x6 to find the first area of the rectangle. Then I have to multiple 5x5 to find the area of the second square. Then I just have to add the answer of the first answer to the second answer is 54+25.
hope this helps!
now, if we take 2000 to be the 100%, what is 2200? well, 2200 is just 100% + 10%, namely 110%, and if we change that percent format to a decimal, we simply divide it by 100, thus .
so, 1.1 is the decimal number we multiply a term to get the next term, namely 1.1 is the common ratio.
