Final answer:
The length of the sides of the square is 8.625 feet.
Step-by-step explanation:
To find the length of the sides of the square, we can use the formula for the perimeter of a square, which is P = 4s, where P is the perimeter and s is the length of a side. In this case, the perimeter is given as 34.5 feet. So, we can set up the equation 34.5 = 4s and solve for s. Dividing both sides by 4, we get s = 8.625 feet. Therefore, the length of the sides of the square is 8.625 feet.
