<u>Given:</u>
A rectangular driveway is 8 feet wide and it has an area of 112 square feet.
We need to determine the length of the driveway.
<u>Length of the driveway:</u>
The length of the driveway can be determined using the formula,
where Area = 112 square feet and width = 8 feet.
Substituting the values, we have;
Dividing both sides by 8, we get;
Hence, the value of the length is 14 feet.
Thus, the length of the driveway is 14 feet.

<h2>Answer:</h2>
The expression which represents the perimeter P of the rectangle as a function of L is:
The length and width of a rectangle are denoted by L and W respectively.
Also the diagonal of a rectangle is: 10 inches.
We know that the diagonal of a rectangle in terms of L and W are given by:
( Since, the diagonal of a rectangle act as a hypotenuse of the right angled triangle and we use the Pythagorean Theorem )
Hence, we have:
But we know that width can't be negative. It has to be greater than 0.
Hence, we have:
Now, we know that the Perimeter of a rectangle is given by:
Here we have:
