I need help with this question

120m²

Step-by-step explanation:

you need to find the area of each surface on the triangular prism. there are 5 faces so we need to find the area of all 5.

since there are two triangles you can take the area of the first triangle and multiply it by 2 in one equation

combined triangle areas:

A= 2 (1/2bh)

A=bh

A=3(4)

A=12m²

9 x 5 rectangle:

A=bh

A=9(5)

A=45m²

9 x 4 rectangle:

A=bh

A=9(4)

A=36m²

9 x 3 rectangle:

A=bh

A=9(3)

A=27m²

add all the areas together to get 27+36+45+12=120m²

the line of

whatvare the choices
