Answer:
Explanation:
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
