Answer:
Your measurements; Area = 216.108 cm²
Another student's measurements; Area = 216.9404 cm²
- Difference in area could be as a result of human error or perhaps that they made use of different measuring tools.
Step-by-step explanation:
For Your measurements;
Length of rectangle = 20.70 cm
Width of rectangle = 10.44 cm
Area of rectangle is given by; A = length × width = 20.7 × 10.44 = 216.108 cm²
For Another student's measurements;
Length of rectangle = 20.74 cm
Width of rectangle = 10.46 cm
Area = 20.74 × 10.46
Area = 216.9404 cm²
The areas they both obtained are not of equal values and this could be as a result of human error or perhaps that they used different measuring tools.
Answer:
Options B and D.
Step-by-step explanation:
The general form of sine function
where, |A| is amplitude, 
is period, 
is phase shift and D is y-intercept.
The general form of cosine function
where, |A| is amplitude, is period, is phase shift and D is y-intercept.
In function, 
Amplitude : 
y-intercept : -1
In function, 
Amplitude : 
y-intercept : -1
In function, 
Amplitude :
y-intercept : 0
In function, 
Amplitude :
y-intercept : -1
Therefore, the correct options are B and D.

Answer: what u mean lol
Step-by-step explanation:
Answer:
9 cm^2
Step-by-step explanation:
If the perimeter of the square is 12 cm, then the length of ONE side is (1/4) of that, or 3 cm.
The area of this square is A = s^2, where s is the length of one side.
Here we have A = (3 cm)^2 = 9 cm^2.
