The answer to your question is below
Step-by-step explanation:
Process
-Calculate the area of the 6 faces and compare the result with the choices.
1.- Area of Face A
Area = 14 x 8 = 112 m² True
2.- Area of face B
Area = 6 x 14 = 84 m² False
3.- Area of face C
Area = 10 x 14 = 140 m² True
4.- Area of face D
Area = 6 x 8/2 = 24 m² True
5.- Area of face E
Area = 6 x 8/2 = 24 m²
The last choice False
Answer:
Area of trapezium = 16.5 cm^2
Step-by-step explanation:
Given:
a = 5 cm
b = 6 cm
h = 3 cm
To Find:
Area of trapezium = ?
Solution:
Area of trapezium = h(a + b)/2
Area of trapezium = 3(5 + 6)/2
Area of trapezium = 3 x 11/2
Area of trapezium = 33/2
Therefore, Area of trapezium = 16.5 cm^2

Hey!
The formula of direct variation is y = kx. So we know that p = kr^2
Hint: after it says varies, it's basically the equal sign.
so we can set it up
56 = 4^2k
56=16k
now we want k alone so we have to divide 16 on both sides
k=3.5
We can now solve for p like it asks
p = 3.5*6^2
p=126
There's your answer!
Hope this helps!
