Answer:
Area of Triangle A = 4 cm²
Area of Rectangle = 24 cm²
Area of Triangle B = 4 cm²
Area of Trapezoid = 32 cm²
Step-by-step explanation:
The formula to find the area of a triangle is: 
The base (b) is 2 and the height (h) is 4.
Now multiply,
2 times 4 = 8
Then divide,
which equals 4.
So the area of Triangle A and B is 4 cm² because they are the same triangles.
The formula to find the area of a rectangle is: a times b.
a=6 and b=4
Multiply,
6 times 4 = 24
So the area of the rectangle is 24 cm²
The formula to find the area of a trapezoid is: 
A=6
B=10
H=4
So now,

6+10=16
16 divided by 2 is 8.
Last multiply,
8 times 4 is 32.
The area of the trapezoid is 32 cm²
Hope this helped! And have a great day!
No, in order for this to be correct, you'd have to move BOTH decimals in the same direction the same amount of places.<span />
Well, it says to use a calculator to calculate them. So a calculator I would highly recommend is the Desmos graphing calculator.
The answer is 3
6r+2
R=1/6
6(1/6)+2
1+2=3
∴
=2796202.5
