Answer:
B)
Step-by-step explanation:
That is a triangular prism and thus, it has two bases that are triangles, in this case, right triangles, whose hypotenuse is 5 in. long and one of its legs is 4 in. and the other one, 3 in.
The first step is to find the area of both bases like this:
The second step is to get the lateral area, which is compound of three rectangles, hence the process is the following:
Finally, we sum both of the areas found to calculate the total area.
So, the answer is option B).
