To find the width of each side of the shelter, we can use the information provided.
Let's denote the width of each side as \( w \).
The total length of the three sides is given as 6 feet, which is equal to 72 inches (since 1 foot = 12 inches): \[ \text{Total length} = 72 \text{ inches} \] The length of the back wall is 3.25 feet, which is equal to 39 inches (3.25 feet x 12 inches/foot): \[ \text{Length of back wall} = 39 \text{ inches} \]
Since the total length consists of the back wall and the two widths: \[ \text{Total length} = \text{Length of back wall} + 2 \times \text{Width} \ 72 = 39 + 2w \]
Now we can solve for \( w \): \[ 72 - 39 = 2w \ 33 = 2w \ w = \frac{33}{2} = 16.5 \text{ inches} \]
Thus, the length of each side (width) is 16.5 inches.
The correct response is: Each side is 16 1/2 inches.
