Answer:
20,4
Step-by-step explanation:
Suppose that x, y are the the length and width
Area=x*y=80
Parameter=2(x+y)=48....x+y=24
Xy=80...x(24-x)=80...x=20,y=4
The number:

is going to be between the numbers 563 and 564; since 10 squared equals 100 and the decimal point will move to places to the right.
Therefore, the answer is D.
165 - 57 and divide that by 2. So that would be 54
To obtain a more accurate answer! :)
Let's just change your problem to 147 of 30%
"Of" is always equaling to multiplication (×)
Now, it would be easier to simplify
30% (147)
30% ÷ 100 = 0.3
0.3(147)
Now, we get to your answer which might be 44.1
