The width of a rectangle is 3 feet shorter than its length. the perimeter is 530 feet. let x equal the length of the rectangle. the formula is p = 2l + 2w. what are the length and the width of the rectangle? a. write a list of the known information and the unknown information. write an algebraic equation to show the relationship between the knowns and the unknowns. solve the equation.

1) Known information:

- The perimeter.

-

- The formula of the perimeter of the rectangle:

Unknown information:

- The value of the widht.

- The value of the length.

2) Equation:

3)

Step-by-step explanation:

1. The problem gives you the perimeter, the formula of the perimeter of a rectangle and says that the width of a rectangle is 3 feet shorter than its length (), but does not give the value of the widht and the value of the lenght.

2. Based on the information given, you can write the following equation:

Where is the lenght and is the width.

Substitute into the equation above, then you have:

3. Solve for the lenght:

4. Know you can calculate the width:

5. Therefore, the length is 134 feet and the widht is 131 feet.
