Introduction

In this problem, we are given a rectangle with a variable area and a fixed width. The area of the rectangle is given as $24 + 30m$ , where $m$ is a variable, and the width is given as $6$ . Our goal is to find the length of the rectangle.

Drawing a Sketch of the Rectangle

To start, let's draw a sketch of the rectangle. Since we know the width is $6$ , we can draw a rectangle with a width of $6$ units.

Understanding the Area of a Rectangle

The area of a rectangle is given by the formula $A = lw$ , where $A$ is the area, $l$ is the length, and $w$ is the width. In this case, we are given the area as $24 + 30m$ and the width as $6$ . We can set up an equation using the formula:

24 + 30m = 6l

Solving for the Length

To solve for the length, we can start by isolating the variable $l$ on one side of the equation. We can do this by dividing both sides of the equation by $6$ :

\frac{24 + 30m}{6} = l

Simplifying the left-hand side of the equation, we get:

4 + 5m = l

Finding the Value of m

However, we are not given a specific value for $m$ . To find the length of the rectangle, we need to find the value of $m$ . Unfortunately, we are not given any additional information about $m$ , so we cannot find a specific value for the length.

Conclusion

Alternative Approach

One possible approach to this problem is to recognize that the area of the rectangle is a linear function of the variable $m$ . This means that the graph of the area function will be a straight line. We can use this information to find the value of $m$ that corresponds to a specific area.

Graphing the Area Function

To graph the area function, we can start by plotting a few points on the graph. For example, if $m = 0$ , the area is $24$ , so we can plot the point $(0, 24)$ . If $m = 1$ , the area is $54$ , so we can plot the point $(1, 54)$ .

  +---------------+
  |               |
  |  (0, 24)     |
  |               |
  +---------------+
  |               |
  |  (1, 54)     |
  |               |
  +---------------+

Finding the Value of m

We can use the graph to find the value of $m$ that corresponds to a specific area. For example, if we want to find the value of $m$ that corresponds to an area of $48$ , we can look at the graph and see that the point $(2, 48)$ is on the graph.

Conclusion

In this problem, we were given a rectangle with a variable area and a fixed width. We were able to set up an equation using the formula for the area of a rectangle and solve for the length. However, we were not given a specific value for the variable $m$ , so we were unable to find a specific value for the length. We also explored an alternative approach to the problem, which involved graphing the area function and finding the value of $m$ that corresponds to a specific area.

Final Answer

Unfortunately, we were unable to find a specific value for the length of the rectangle. However, we were able to set up an equation using the formula for the area of a rectangle and solve for the length in terms of the variable $m$ . We also explored an alternative approach to the problem, which involved graphing the area function and finding the value of $m$ that corresponds to a specific area.
