To answer this question, we need to find the area of the triangle of the prism, and then the area of the three other rectangles.

Finding the area of the triangle

We have that the area is given by the height of the triangle, in this case, h = 16cm (we can see that this segment is perpendicular to the base), and the length of the base is equal to b = 24. Then, we can calculate the area of this triangle as follows:


A_{\text{triangle}}=(b\cdot h)/(2)=(24\cdot16)/(2)=(384)/(2)\Rightarrow A_(triangle)=192Finding the area of one of two congruent rectangles
