Atriangular prism has a height of 9 meters and a triangular base with the following dimensions.

what is the surface area of the prism?

372 m2
324 m2
504 m2
420 m2

The surface area of the prism is

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to

where

B is the area of the triangular base

P is the perimeter of the triangular base

H is the height of the prism

we have

Find the area of the triangular base

The area is equal to

see the attached figure to better understand the problem

Find the perimeter of the triangular base

The perimeter is equal to

substitute the values

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.
