Answer:
Option C is correct.
Step-by-step explanation:
Let the length be L
Let the width be W
The length of a rectangular floor is twice its width.
So, we get 
The length of the carpet is L
Carpet width is 2 feet less than the room, so 
Area of the carpet = 160 sq feet
We get :

As L=2W, we get

=> 
Equating to zero, we have

Taking out 2 common

=> 
=> 
We get roots as : (W-10) and (W+8)
Hence, W = 10 and W = -8(neglect this negative value)
Now, the width = 10 feet
Length =
feet
Hence, option C is the answer.
Answer:
9 feet
Step-by-step explanation:
Area of a parallelogram = base times height
Thus, 54 = 6h
where h = height
* divide each side by 6 *
54 / 6 = 9
6h / 6 = h
h = 9
Thus, the answer is A

I'm sorry but the solution you proposed was a bit hard to follow, so I'll just post my solution: we convert "2 and 1/2" to a single fraction:

So, we know that 5/2 gallons cost 60 dollars, which means

To find the cost of a single gallon, we have to solve the equation for g:
