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

• A. 15 cm
• B. 20 cm
• C. 25 cm
• D. 30 cm

Answer: (B)

To find the perimeter of a square, you need to use the formula for the perimeter, which is the sum of all four sides. Since all sides of a square are equal, the formula can also be expressed as: Perimeter = 4 × side length In this case, the side length of the square is given as 5 cm. So, you would calculate the perimeter as follows: Perimeter = 4 × 5 cm = 20 cm Thus, the perimeter of the square is 20 cm, confirming that the correct answer is indeed the one that states this measurement. Understanding the formula for the perimeter of a square is essential for solving similar problems involving geometric figures.
