    Let's use l to denote length and w to denote width. What is the formula for computing the area of a rectangle given its length and width?

    \[Area = l \times w\]

    \[l = w + 8\]

    Length is always longer than the width. In this case, the length is exactly 8cm longer than the width.

    We can then express the area of this rectangle in either length only or width only.

    \[Area = l \times (l-8) = w \times (w+8) = 48\]
