After applying the rainfall factor, what is the adjusted flat area?

4,450 sft

4,500 sft

4,950 sft

When you adjust for rainfall, you multiply the base flat area by the rainfall factor to account for the extra surface area affected by precipitation. If the starting flat area is 4,500 square feet and the rainfall factor is 1.10, you calculate 4,500 × 1.10 = 4,950 square feet. So the adjusted flat area is 4,950 sft. This shows how the rainfall factor scales the plan area to reflect rainfall impact on drainage and coverage needs.

5,000 sft
