The square was divided into 2 identical parts. The perimeter of the square is 48 cm. What is the perimeter of each half of the square?

Since all sides of a square are equal, its perimeter is the sum of four equal sides. We calculate the length of the side of the square:

48: 4 = 12 (cm).

After dividing the square, two equal rectangles turned out, two sides of which are equal to the side of the square, and two are half as large. Find the smaller side of such a rectangle:

12: 2 = 6 (cm).

We calculate the perimeter of the rectangle – half of the square:

P = 2 * (12 + 6) = 2 * 18 = 36 (cm).

Answer: The perimeter of half of the square is 36 cm.
