Answer:


LA=755\ m^(2),
SA=785\ m^(2)

Explanation:

Part 1) Find the lateral area of the given prism

we know that

The lateral area of the prism is equal to


LA=PL

where

P is the perimeter of the triangular base

L is the length of the prism

Find the perimeter P


P=5+6+11.21=22.21\ m

we have


L=34\ m

substitute


LA=(22.21)(34)=755\ m^(2)

Part 2) Find the surface area of the given prism

we know that

The surface area of the prism is equal to


SA=2B+LA

where

B is the area of the triangular base

LA is the lateral area of the prism

Find the area B


B=(1/2)(5)(6)=15\ m^(2)

we have


LA=755\ m^(2)

substitute


SA=(2)(15)+755=785\ m^(2)
