Explanation
We want to find the total surface area of the 3d figure given .
1. The figure is a prism.
The perimeter of the base is 14.
Thus, the lateral surface area is,
[tex]\begin{gathered} LSA=Perimeter\text{ }of\text{ }base\times height\text{ }of\text{ }prism \\ LSA=14\times11=154square\text{ units} \end{gathered}[/tex]The total surface area is thus;
[tex]\begin{gathered} TSA=LSA+2(BASE\text{ }AREA) \\ =154+2(19) \\ =192\text{ square units} \end{gathered}[/tex]Thus, the total surface area is 192 square units.
