Answer:
228
Step-by-step explanation:
[Formulas Below]
Surface area means the sum of all the shapes on the figure, which means we have to calculate each area of the shapes on the triangular right prism and add them up. To calculate the triangles, we plug in 6 and 5 and get 15. Since there are 2 triangles, we multiply it by 2. Next, we have to find the areas of the rectangles. 11 * 6.5 = 71.5 (There are two of them so you multiply by 2), and 11 * 5 = 55. Finally, we add all of these up. 15 * 2 + 71.5 * 2 + 55 = 30 + 55 + 143 = 228. The surface area is <u><em>228</em></u>.
<u><em>Area of Triangle = (Length * Height)/2</em></u>

<u><em>Area of Rectangle = Length * Width</em></u>
The y-axis runs vertically, so changing the y-coordinate moves a figure up or down. Adding a number to the y-coordinate shifts the image up, while subtracting a number shifts the figure down.
So to translate 3 units down, we just subtract 3 from the y-coordinate.
Instead of (-2, 1) it's now (-2, -2) since 1 - 3 (units) = -2
Now, another way to say "reflect across the y-axis" is to say "reflect across the line x=0" since the line created by graphing x=0 is the same as the y-axis.
An image that is a reflection across the y-axis, or across the line x=0, will have opposite x-coordinates from the pre-image but identical y-coordinates.
Therefore, the rule for reflecting an image across the y-axis can be described as (x, y) → (−x, y).
So using our translated point (-2, -2) it now becomes (2, -2).
You didn't provide an image, however, all you need to find is the translated and reflected point that lies on (2, -2).
