Answer:
Part 1) The surface area of the triangular prism is 
Part 2) The surface area of the trapezoidal prism is 
Step-by-step explanation:
Part 1) Find the surface area of the triangular prism
we know that
The surface area is equal to

where
B is the area of the triangular base of the prism
P is the perimeter of the base of the prism
L is the length of the prism
<u>Find the area of the triangular base B</u>

<u>Find the perimeter of the base P</u>


substitute the values

Part 2) Find the surface area of the trapezoidal prism
we know that
The surface area is equal to

where
B is the area of the trapezoid base of the prism
P is the perimeter of the base of the prism
L is the length of the prism
<u>Find the area of the trapezoid base B</u>

<u>Find the perimeter of the base P</u>


substitute the values
