Final answer:
The perimeter of a square with sides of length 17.5 cm is 70 cm.
Step-by-step explanation:
To find the perimeter of a square, we add up the lengths of all its sides. Since a square has four equal sides, we can multiply the length of one side by 4 to find the perimeter. In this case, the length of each side is 17.5 cm, so the perimeter of the square is 17.5 cm + 17.5 cm + 17.5 cm + 17.5 cm = 70 cm.
