4 11/2
Step-by-step explanation:(X₁, Y₁) is the coordinates of the 1st point and (X₂, Y₂) is the coordinates of the 2nd point.
Using the formula above,.
The formula for finding the lateral area for a triangular prism is

So put in the values and you get


The formula for finding the surface area of a triangular prism is
SA = bh + (s1 + s2 + s3)H
So put in all the values and you get
SA = 9(8) + (9 + 8 + 12.04)23
SA = 740
Hope this helps! :)
