we know that

The surface area of a triangular prism is equal to

SA=2B+PL

where

B is the area of the triangular face

P is the perimeter of the triangular face

L is the length of the prism

step 1

Find the area B

B=(1/2)*y*h

substitute the given values

B=(1/2)*11*4

B=22 units^2

step 2

Find teh value of P

P=X+X+y

substitute the given values

P=7+7+11

P=25 units

step 3

Find the surface area

SA=2*22+25*14

SA=394 units^2
