            I will show you how to solve it MENTALLY.

Let W is the width. Then 3W - 2 is the length. The area is W*(3W-2) = 48. Multiply both sides by 3 3W*(3W-2) = 48. So, the number 48 is presented as the product of two factors what differ by 2. If you think 5 seconds, you guess these numbers: 6 and 8. Hence, 3W = 8 and then W = = 2 .

That's all.
