To find the width of the shelter, we need to first establish the relationships between the given lengths.
- We know that the back wall (length) is 3.25 feet.
- Let \( w \) be the width of each of the two sides.
According to the problem, the total length of all three sides is 6 feet. The equation for this would be:
\[ 3.25 + w + w = 6 \]
This simplifies to:
\[ 3.25 + 2w = 6 \]
Next, we can solve for \( w \):
- Subtract 3.25 from both sides:
\[ 2w = 6 - 3.25 \] \[ 2w = 2.75 \]
- Divide both sides by 2:
\[ w = \frac{2.75}{2} = 1.375 \text{ feet} \]
Now, converting 1.375 feet to inches (since there are 12 inches in a foot):
\[ 1.375 \text{ feet} \times 12 \text{ inches/foot} = 16.5 \text{ inches} \]
Therefore, the width of each side is 16.5 inches.
Now looking at the options provided:
- Each side is 16 12 inches
- Each side is 16 1 half inches
- Each side is 14 12 inches
- Each side is 14 1 half inches
- Each side is 19 12 inches
- Each side is 19 1 half inches
- Each side is 15 inches
The correct response is: Each side is 16 1 half inches.
