Answer:
Part 1) The area of the figure is 
Part 2) The perimeter of the figure is 
Step-by-step explanation:
Part 1) Find the area of the figure
we know that
The area of the figure is equal to the area of three squares
so
![A=3[4^2]=48\ cm^2](https://tex.z-dn.net/?f=A%3D3%5B4%5E2%5D%3D48%5C%20cm%5E2)
Part 2) Find the perimeter of the figure
we know that
The perimeter of the figure is equal to two times the length side of the square, plus the circumference of six semicircles ( or the circumference of three circles)
Remember that
The circumference of a circle is equal to
where
D is the diameter of the circle
In this problem
so
![P=2(4)+3[\pi(4)]=(8+12\pi)\ cm](https://tex.z-dn.net/?f=P%3D2%284%29%2B3%5B%5Cpi%284%29%5D%3D%288%2B12%5Cpi%29%5C%20cm)
simplify
Answer:
$638.14
Step-by-step explanation:
Our equation is 
, with p being the starting amount, x being the interest rate, and t being the time. Plugging our variables in, we get
= around 638.14
Answer: 37 you just add the two in that case
#2 because it’s a Pythagorean theorem triple
