Width= 8 cm
Because 192 / 2 = 96 / 12 = 8
SA= (perimeter * height) + 2 (length * width)
SA= (20*12)+2(2*8)
SA= 240+32
SA= 272 cm2

Answer:
Glide Reflection: It is a composition of transformations.
In glide reflection, a translation is first performed on the figure then it is reflected over a line.
Given:
The coordinate of A = (-3,-3)
The rule of translation is and the line of reflection is y=1.
Now,
First applying the rule of translation we get;
= (2 , -3)
Since, -3 which is 4 unit below the line of reflection,
then,
after the reflection, over the line y=1 we get, the reflected point A' would be 4 units above the line of reflection
so, A' (2, 1+4) =(2,5)
Therefore, the coordinate of A' (2,5).
Hello there!
To find the slope of a line, we need to know at least two points contained in the graph of the line.
The slope of a line passing through the points and is given by the formula: .
As we can see on the graph, two points contained on the line are and .
Using the formula above, we get that:
Subtract the values on both numerator and denominator of the fraction
This is the slope of this line we were looking for and is the answer contained on the 4th option.
