What is the perimeter of a square with a side length of 5 cm?

• A. 10 cm
• B. 15 cm
• C. 20 cm
• D. 25 cm

Answer: (C)

To find the perimeter of a square, you use the formula for perimeter, which is \( P = 4s \), where \( s \) represents the side length of the square. In this case, the side length is given as 5 cm. Plugging the value into the formula, we calculate: \[ P = 4 \times 5 \text{ cm} = 20 \text{ cm} \] Hence, the perimeter of the square is indeed 20 cm. This shows the application of the perimeter formula for a square based on its side length, confirming that when you multiply the side length by 4, you get the total distance around the square.
