Find the surface area of this composite solid.

a.93 m^2
b.111 m^2
c.84 m^2
d.102 m^2

it’s 93cm^

Step-by-step explanation:

remember that the bottom of the triangular prism/top base don’t count as surface area.

first equation for the surface of the triangular prism: 1/2ps = 1/2•12•4 = 24m

add it to the surface area of the rectangular prism: 3•3 + 5•3•4 = 69m

then simply add them

your answer is 93m^!
