Answer:
108 in²
Explanation:
The area of the recycled part can be calculated as the difference between the area of the sheet of paper and the area of the triangle.
So, the area of the sheet of paper can be calculated as:
Ar = Base x Height
Ar = 10 in x 12 in
Ar = 120 in²
Then, the area of the triangle can be calculated as:
At = (1/2) x Base x Height
At = (1/2) x 6 in x 4 in
At = 12 in²
Therefore, the area of the recycled part is equal to:
A = Ar - At
A = 120 in² - 12 in²
A = 108 in²
So, the answer is 108 in²
