Matthew is cutting construction paper into rectangles for a project. He needs to cut one rectangle that is 12 inches x 14 1/4 inches. He needs to cut another rectangle that is 10 1/2 inches by 10 1/4. How many total square inches of construction paper does Matthew need for his project? PLEASE HELP ME FOR REAL!!!

I got 278 5/8

Step-by-step explanation:

the question stated square inches which I referred

to as area. You multiply both rectangles than add them together. I may be wrong but I hope this gives you a lead! :)

Step-by-step explanation:

1) Multiply the sides of each piece of paper. (12 × 14 1/4 = 171) and (10 1/2 × 10 1/4 = 107 5/8)

2) Add your answers together. (171 + 107 5/8 = 278 5/8)

I hope this helped!
