Understanding the Formula

The calculator uses the following formula to calculate the total area of a gable roof:

Area = 2 * (0.5 * length * height) + (0.5 * width * height)

This formula accounts for the two triangular sections of the gable roof and the rectangular section in the middle.

Example

If your house is 40 feet long, 30 feet wide, and the roof is 12 feet high:

Area = 2 * (0.5 * 40 * 12) + (0.5 * 30 * 12) = 480 + 180 = 660 sq ft
