The equation is

#### Explanation:

First, we know that the area of a rectangle is equal to length times width, or

We know the area and the width, so we can solve the length.

The definition of a **linear equation** is simply an equation where when two points are plotted on a graph, you can make a straight line through the two points. Another way to state this is that it has a max of one unknown/variable.

First, let's plug in our values into the rectangle formula:

Now, we need

Therefore, the linear equation is:
