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 **6****w** = 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:

w= 5 in

Step 5

Therefore, the answer is D.
