The answer would be 3.1428
I'll give you a few hints. Area of a rectangle is length times width. We know that length times width is 135 sq ft, so we can express it as:
<span>L * W = 135 </span>
<span>Now, L is 6 feet longer than width (L = 6 + W). Something tells me this is going to involve a quadratic formula then plugging in values into our original equation. </span>
Answer: 14 gallons
Step-by-step explanation:
Let's call the total gallons of gas Abdul's tank can hold <em>x</em>.
Then, based on the information given in the problem, you can write the following expression:

Therefore, when you solve for x, you obtain the following result:

X=14 because it is half of 28
