The perimeter of a bookmark is 16 centimeters. The bookmark is 6 centimeters tall. How wide is it?

1 answer

To find the width of the bookmark, we can use the formula for the perimeter of a rectangle, which is given by:

\[ P = 2 \times (\text{length} + \text{width}) \]

In this case, the perimeter \( P \) is 16 centimeters, and the height (length) of the bookmark is 6 centimeters. We need to find the width.

Let's denote the width as \( w \). Plugging the known values into the perimeter formula:

\[ 16 = 2 \times (6 + w) \]

Now, we can simplify and solve for \( w \):

  1. Divide both sides of the equation by 2:

\[ 8 = 6 + w \]

  1. Subtract 6 from both sides:

\[ w = 8 - 6 \]

  1. Simplifying gives:

\[ w = 2 \]

Thus, the width of the bookmark is 2 centimeters.
