Question 2 (3 points) Saving...

Answer 1

Answer:

Option C) 144 centimeters squared.

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The surface area of a prism is equal to

$SA=2B+PL$

where

B is the area of the base of the prism

P is the perimeter of the  base

L is the length or height of the prism

Find the area of the base B

$B=\frac{1}{2}(3)(4)=6\ cm^2$ ---> the base is a right triangle

Find the perimeter of the base P

$P=3+4+5=12\ cm$ ---> is the perimeter of a triangle

we have

$L=11\ cm$

Find the surface area SA

$SA=2(6)+12(11)=144\ cm^2$
