What is the area of a roof expressed in squares, according to typical measurements?

The area of a roof is typically measured in squares, where one square is equivalent to 100 square feet. Therefore, when determining the area of a roof, the total square footage is divided by 100 to convert it into squares.

In the context of the question, if the area of the roof is expressed as 85 squares, this means the total area would be 8,500 square feet (85 squares multiplied by 100 square feet per square). This allows for an understanding that the most common measurements used in the roofing industry rely heavily on the square concept for efficiency and ease in estimating materials and costs.

When evaluating the other options, while some may present figures close to this standard, only the option of 85 squares matches the context and definition used within the industry for such measurements.
