Answer: A) 0.18 cm²
Step-by-step explanation:
To calculate the area of a parallelogram you must apply the formula shown below:

Where b is the base and h is the height of the parallelogram.
You know the values of the base and the value of the height.
Therefore, when you susbstitute these values into the equation shown above, you obtain the following result:

T = large candles and s = small candles
3t + 5s = 6.40
4t + 6s = 7.50
^^ this would be ur system of equations
The graph is a function because when you use the vertical line test it does not hit more than one point at any given place on the line.
Hope this helped :)
