[1 foot = 12 inches; 1 yard = 3 feet] 3 feet 5 feet 8 feet 10 feet

5 feet

Step-by-step explanation:

Let w be the width of portion.

Given: The length of the rectangular portion = 12 feet

We know that 1 yard = 3 feet

Then 1 feet =

The length of the rectangular portion =  

The height of the rectangular portion = 6 inches

1 yard = 36 inches

Then 1 inch =

The height of the rectangular portion =  

Now, the volume of the portion ( in cubic yards) :-

The total cost of the concrete will be :-

In feet ,

Hence, the width of the portion of the driveway on which Paul plans to put concrete is about 5 feet.
