A roof measures 884 square feet. How many squares of shingles must you buy to re-roof the structure?

The correct answer is: 9

To determine how many squares of shingles are needed to cover a roof measuring 884 square feet, it is essential to understand what a "square" means in roofing. One square of shingles covers an area of 100 square feet. To find out how many squares are required for a roof of 884 square feet, the calculation is straightforward: Divide the total area of the roof (884 square feet) by the area covered by one square of shingles (100 square feet). This calculation would be: 884 square feet ÷ 100 square feet/square = 8.84 squares. Since you cannot purchase a fraction of a square, you would round up to the next whole number, which is 9. Thus, you would need to buy 9 squares of shingles to adequately cover the roof. This understanding of how to convert total area into squares and the necessity of rounding up is crucial for ensuring that enough material is purchased for the roofing project.
