43/21 as a decimal rounded to the nearest hundreth

2.05

Step-by-step explanation:

43/21 = 2.047 ≈ 2.05

The 4 is in the hundredths place, so you would look at the right of the 4 to determine what to round it to.

If it is 0-4 keep it the same

If it is 5-9 up it by one.

Example,

5.903 = 5.90

6.389= 6.39

Since perimeter means all around it just means adding all the sides. Because you are given length and width your equation would then be, " (5)+(5)+(2x=14)+(2x+14). Now since area means length times width you would multiply length times width. Since x=7 you would multiply 7x5 and the area equals 35. Questions 35-37 are indeed correct. You're smart ! By the way I'm twelve so hopefully you found this helpful.
