To find the width of each side of the shelter, we start with the information given:
- The length of the back wall is \(3.25\) feet.
- The total length of all three sides is \(6\) feet.
- The two other sides (width) are the same length.
Let's denote the width of each side as \(w\). The total length of all three sides can be expressed as:
\[ \text{Total length} = \text{Back wall} + \text{Width} + \text{Width} = 3.25 + w + w = 3.25 + 2w \]
Since the total length of all three sides is \(6\) feet, we can set up the equation:
\[ 3.25 + 2w = 6 \]
Now, let's isolate \(2w\):
\[ 2w = 6 - 3.25 \] \[ 2w = 2.75 \]
Now, divide both sides by \(2\):
\[ w = \frac{2.75}{2} = 1.375 \text{ feet} \]
To convert \(1.375\) feet to inches (since \(1\) foot = \(12\) inches):
\[ 1.375 \text{ feet} \times 12 = 16.5 \text{ inches} \]
Converting to a mixed number, \(16.5\) inches is the same as \(16 \frac{1}{2}\) inches.
So, the length of each side (width) is \(16 \frac{1}{2}\) inches.
The correct response is:
Each side is 16 12 inches.
