How to find the area of a square: The area of a square can be found by multiplying the base times itself. This is similar to the area of a rectangle but the base is the same length as the height. If a square has a base of length 6 inches its area is 6*6=36 square inches.
Multiply the width x length to obtain the house area in sq ft. if your house isnât square or rectangle, compute each piece then total the sums. Example: a 50 x 30 ft (length x width) = 1500 sq ft. To get the roof size, convert the sq ft area to roofing squares. Assuming the area is 1500 sq ft, it should be divided by 100 (100 is always the number to use). The answer is 15 squares.
