Explanation:

Step1: Set up rate calculation

We need to find gallons per square foot, so divide total gallons by total square feet.
$\text{Rate} = \frac{\text{Total Gallons}}{\text{Total Square Feet}}$

Step2: Substitute values and compute

Plug in 2 gallons and 400 square feet.
$\text{Rate} = \frac{2}{400} = \frac{1}{200}$

Answer:

$\frac{1}{200}$ of a gallon of stain per square foot of deck
