The formula for determining the area of a rectangle is expressed as

Area = length * width

She needs to cut one rectangle that is 20 inches times 12 1/4 inches. It means the area of this rectangle would be

12.25 * 20 = 245 squared inches

She needs to cut another rectangle that is 10 1/3 inches by 10 1/4 inches. Converting both dimensions to improper fraction, it becomes 31/3 inches and 41/4 inches. The area of this rectangle would be

31/3 * 41/4 = 105.92 square meters

The total square inches of construction paper that Irene need for her project is

245 + 105.92 = 350.92 squared inches
