Step by Step Solution

Step 1

The picture below shows the rectangle with the length of 6in and the width of w.

Step 2

Since the value of the area is given as 30in^{2}, we can substitute A with 30. Similarly, since the length is given as 6in, we can substitute l with 6. This is shown below:

Step 3

Now, we have 6w = 30. Notice that, to find w, we need to remove 6. We can do so by dividing both sides of the equation with 6.

Step 4

Now, the calculated number 5, has no meaning until we include the unit for it. Since the area is in inch^{2}, w will be in inch. Hence:
