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!

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
