To find the surface area of a triangular prism-shaped tent, we need to calculate the surface area using the given dimensions. A triangular prism has a triangular base and three rectangular sides.
### Step 1: Determine the Area of the Triangular Base
Given:
- Height of the prism (tent) = 9 feet
- Base width = 20 feet
- Hypotenuse (slant height) = 13.45 feet
The area \( A \) of a triangle is calculated by:
\[
A = \frac{1}{2} \times \text{base} \times \text{height}
\]
In our case, we can assume the base is 20 feet and the height (vertical height) from the base to the top of the triangle is 9 feet:
\[
A = \frac{1}{2} \times 20 \times 9 = 90 \text{ square feet}
\]
### Step 2: Calculate the Area of the Rectangular Sides
The rectangular sides are formed by:
1. Two rectangles based on the height and length of the prism.
2. One rectangle based on the height and the hypotenuse.
The area of two rectangular sides:
- Base width = 20 feet
- Height = 9 feet
Each rectangle will have an area:
\[
\text{Area of each rectangle} = \text{width} \times \text{height}
\]
For the two rectangular sides:
\[
\text{Area of two rectangles} = 2 \times (20 \times 9) = 2 \times 180 = 360 \text{ square feet}
\]
The area of the rectangle from the hypotenuse:
\[
\text{Area from hypotenuse} = \text{hypotenuse} \times \text{height} = 13.45 \times 9 = 121.05 \text{ square feet}
\]
### Step 3: Total Surface Area Calculation
Now, we can add the areas together to find the total surface area:
\[
\text{Total Surface Area} = \text{Area of triangle} + \text{Areas of two rectangular sides} + \text{Area from hypotenuse}
\]
\[
\text{Total Surface Area} = 90 + 360 + 121.05 = 571.05 \text{ square feet}
\]
### Conclusion
Since 571.05 square feet is not one of the options presented, let's reassess. We may need to evaluate using the correct volume computations or clarify if other dimensions were introduced.
Assuming missing parameters or needing more sections to cover, please specify if any dimensions have to be re-evaluated. Given your options seem higher, confirming total include tent covers across base and upper frames or get dimensions checked for respective base fulfillment leads to estimating different.
Feel free to provide any rectifications or refinements in the parameters to get clear calculated results fitting closer to one of offered options.
