To find the width of the shelter, we need to set up the equation based on the information given:
- The back wall (length) of the shelter is 3.25 feet.
- The total length of all 3 sides of the shelter is 6 feet.
- Let the width of each of the two sides be represented as \(w\).
The equation based on the total length of the three sides is: \[ 3.25 + 2w = 6 \]
Now, we can solve for \(w\):
-
Subtract 3.25 from both sides: \[ 2w = 6 - 3.25 \] \[ 2w = 2.75 \]
-
Divide both sides by 2: \[ w = \frac{2.75}{2} \] \[ w = 1.375 \text{ feet} \]
To convert feet to inches (since 1 foot = 12 inches): \[ 1.375 \text{ feet} \times 12 \text{ inches/foot} = 16.5 \text{ inches} \]
Thus, the width of each side is 16.5 inches or 16 1/2 inches.
Among the response options, the correct answer is: Each side is 16 1/2 inches.
