HELP LAST ATTEMPT ( get marked brainliest show work

Answer:
10
Step-by-step explanation:
Since we are dealing with area, we need to multiply 16 1/4 by 11 3/4.
If we do that, we get 190 15/16
So, if we divide 190 15/16 by 20:
[tex]190 \frac{15}{16} / 20 = 9.5[/tex]
You cannot have half a bag however. You will need to round the number to 10.
