Answer:
160 m²
384 m²
Step-by-step explanation:
The area of a trapezium is given by :
A = 1/2(a + b)h
h = height ; a and b = lengths
From the diagram :
A = 1/2(12 + 20)10
A = 1/2(32)10
A = 16 * 10
A = 160 m²
2.)
Area of parallelogram = base * height
Base = 24 ; h = 16
A = 24 * 16
A = 384 m²

Answer: 
Step-by-step explanation:
By definition, the volume of a rectangular prism can be calculated with the following formula:

Where "l" is the length, "w" is the width and "h" is the height of the rectangular prism.
In this case, you can identify that the length, the width and the height of this rectangular prism given in the exercise, are:

Then, knowing its dimensions, you can substitute them into the formula:

Finally, evaluating, you get that the volume of that rectangular prism is:

First, combine the like terms:
-x+8=3
Then, isolate x:
-x=-5
Then, divide by -1:
x=5
