Answer 2

Problem Statement

The problem states that 16 meters of wallpaper were cut from a roll, and there are 20 meters of wallpaper remaining in the roll. The task is to determine how many meters of wallpaper were originally in the roll and create a diagram based on the problem statement.

Solution

To find the original length of the roll, we need to add the length of the wallpaper that was cut to the length of the remaining wallpaper.

Let's denote the original length of the roll as x meters. According to the problem statement, 16 meters were cut from the roll, so we subtract 16 from x. This leaves us with x - 16 meters of wallpaper in the roll.

We are also given that there are 20 meters of wallpaper remaining in the roll. Therefore, we can set up the following equation:

x - 16 = 20

To solve for x, we add 16 to both sides of the equation:

x = 20 + 16

Simplifying the equation, we find:

x = 36

Therefore, the original length of the roll was 36 meters.

Diagram

Here is a diagram representing the problem:

Original Length of Roll: x meters
-----------------------------------
|                                 |
|                                 |
|                                 |
|                                 |
|                                 |
|                                 |
|                                 |
|                                 |
-----------------------------------

After cutting 16 meters from the roll, we have:

Original Length of Roll: x meters
-----------------------------------
|                                 |
|                                 |
|                                 |
|                                 |
|                                 |
|                                 |
|                                 |
-----------------------------------

And with 20 meters remaining in the roll:

Original Length of Roll: x meters
-----------------------------------
|                                 |
|                                 |
|                                 |
|                                 |
|                                 |
|                                 |
