Solution Steps

To find the width of the paper, we can use the formula for the area of a rectangle, which is length multiplied by width. Given the area and the length, we can rearrange the formula to solve for the width.

Solution Approach
  1. Use the formula for the area of a rectangle: Area = Length * Width.
  2. Rearrange the formula to solve for the width: Width = Area / Length.
  3. Substitute the given values (Area = 63 in² and Length = 9 in) into the formula to find the width.
Step 1: Given Information

We are given the length of the paper as \( L = 9 \) inches and the area as \( A = 63 \) in².

Step 2: Area Formula

The area \( A \) of a rectangle can be expressed as: \[ A = L \times W \] where \( W \) is the width of the paper.

Step 3: Solve for Width

Rearranging the area formula to solve for width \( W \): \[ W = \frac{A}{L} \] Substituting the known values: \[ W = \frac{63}{9} \]

Step 4: Calculate Width

Calculating the width: \[ W = 7.0 \]

Final Answer

The width of the paper is \\(\boxed{W = 7.0}\\).

According to one study, the average monthly cell phone bill in a certain country is 70 (up 31% since 2009). If a 22-year-old student with an average bill gives up her cell phone and each month invests the 70 she would have spent on her phone bill in a savings plan that averages a 5% annual return, how much will she have saved by the time she is 60? She will have saved by the time she is 60. (Round to the nearest cent as needed.)
