Solution
B. use a formula
This problem involves calculating the area of a wall to determine the amount of paint needed. This is typically done using a formula. The formula for the area of a rectangle is length times width, so Jim and Lillian would need to multiply the width of the wall by its height to find the total area. Then, they would need to know the coverage rate of the paint they are using (usually listed on the paint can) to determine how much paint they need to cover the entire wall.
