Answer:

Step-by-step explanation:
The formula for calculate the Area of a rectangle is:

Where "l" is the lenght and "w" is the width.
And the formula for calculate the peimeter of a rectangle is:

Where "l" is the lenght and "w" is the width.
We know that the perimeter of the rectangular baking sheet is 58 inches and its area is 201.25 in². Then:

<u>The steps are:</u>
1. Solve for the "l" from the formula
:

2. Substitute
into the formula
and solve for "w":

Applying the Quadratic formula
, we get:

3. Substitute
into
:

4. Substitute
into
:

Therefore, since the value of the lenght of a rectangle must be greater that the value of the width, we can conclude that the lenght and the width of the rectangular baking sheet are:

Answer:
It is not 1,2,3
