EXPLANATION
The given rectangle has area,
It was given to us that, the length of the rectangle is l=(x+8)
To find the width, we need to factor, the expression for the area.
We split the middle term to get,
We now factor by grouping;
We know that area of a rectangle is
Hence the width of the rectangle is,
