Answer: 
Step-by-step explanation:
You need to use the following formula to calculate the volume of Triangular prism:

Where "a" is the area of one triangular base and "h" is the height of the triangular prism.
Calculate "a" with this formula:

Where "b" is the base of the triangle and "H" is the height.
In this case:

Then, substituting values, you get that the area is the following:

Finally, you must substitute values into the formula for calculate the volume of the triangular prism, and you also must substitute
, which is its height:

Answer:
1st
Step-by-step explanation:
The two triangles are similar by AA
Firstly, we can see that angle LKM and QKR are congruent as they are vertical angles.
The second set can be identified by noticing that RM is a transversal through 2 parrallel lines LM and QR. That manes QRK, and LMK alternate interior angles, showing that the angles are congruent. Hence similarity by AA
If they want you to find the perimeter I guess you add all sides so 9+9+9+9+30 = 66
