Find the surface area

The surface area of the 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

so

B=(1/2)(0.9)(1.2)

B=0.54 m2

P=0.9+1.2+1.5

P=3.6 m

L=3.5 m

substitute

SA=2(0.54)+3.6(3.5)

SA=13.68 m2

answer is 13.68 square metersthe length of the prism

so

B=(1/2)(0.9)(1.2)

B=
