Which method is used to calculate roof area by breaking it down into rectangles?

The method used to calculate roof area by breaking it down into rectangles is the Positive Method. This approach involves dividing the roof into multiple rectangular sections, calculating the area of each rectangle separately, and then summing these areas to determine the total roof area. This method is effective for roofs that have simple geometric shapes, allowing for straightforward measurements and calculations.

The Positive Method's strength lies in its simplicity and accuracy when dealing with flat or gently sloped sections of a roof that can be easily represented as rectangles. By focusing on individual, manageable sections, this method also helps reduce the likelihood of measurement errors and can be easily understood and executed by those involved in roofing projects.

In contrast, methods like the Composite Method would involve more complex shapes and combinations, while the Negative Method and Averaging Method do not specifically focus on breaking down areas into rectangles; instead, they employ different techniques that may not lend themselves to straightforward area calculations for roofing.
