Answer:
Option C) 144 centimeters squared.
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The surface area of a prism is equal to
[tex]SA=2B+PL[/tex]
where
B is the area of the base of the prism
P is the perimeter of the  base
L is the length or height of the prism
Find the area of the base B
[tex]B=\frac{1}{2}(3)(4)=6\ cm^2[/tex] ---> the base is a right triangle
Find the perimeter of the base P
[tex]P=3+4+5=12\ cm[/tex] ---> is the perimeter of a triangle
we have
[tex]L=11\ cm[/tex]
Find the surface area SA
[tex]SA=2(6)+12(11)=144\ cm^2[/tex]
