Final answer:
The equation that could be used to find the width of the rectangle is w = (1/3)*I + 2.
Step-by-step explanation:
To find the width of the rectangle, we need an equation that relates the length of the rectangle to its width.
Let's use w to represent the width and I to represent the length.
The problem states that the width is 2 more than one third of the length.
This can be written as: w = (1/3)*I + 2.
