Answer:
A
Step-by-step explanation:
Two Squares
There are 2 squares at the top and bottom. All sides = 3
2* s^2
2 * 3^2
2 * 9
18
Middle Figure.
<u>Triangles</u>
There are many ways to solve this. I think the most easily understood is to break it into 2 triangles and a rectangle.
Base of both triangles = 5 + 5 = 10
The height of each triangle = (7 - 3)/2 = 4/2 = 2. You divide by 2 because there are 2 bases -- one in each triangle.
Area = 1/2 * 2 * 10 = 10
But there are 2 of them so the total area is 20
<u>Rectangle</u>
The length of the rectangle = 5 + 5 = 10
The width = 3
Area = 30
Total
Total Area = 2 squares + 2 triangles + 1 rectangle
Total Area = 18 + 20 + 30 = 68

Answer:
44,280
Step-by-step explanation:
I might know. I multiplied the 1st and got 307.5.
then multiplied the 2d. I got 144
multiplied 307.5x144 and I got 44,280
Answer:
The answer is B. 1 28/99
Step-by-step explanation:
If you divide 28/99, you will get 0.28282828 and so on. and 1 is a whole number, so 1.28 is what B equals.
