How many squares of shingles to cover a 24x50 roof?

To determine the number of squares of shingles needed to cover a 24x50 roof, first calculate the total area of the roof: 24 feet x 50 feet = 1,200 square feet. Since one square of shingles covers 100 square feet, you would divide the total area by 100. Therefore, you would need 12 squares of shingles to cover the roof.
