Two identical rectangles are attached to each other with large sides so that you get a square. The perimeter of this square is 32 cm. Find the perimeter of the rectangle.

It is known that two equal rectangles, attached to each other by their large sides, form a square.

Let’s calculate what the length of the side of the square is equal to:

a = P / 4 = 32/4 = 8 cm.

That is, the large side of the rectangles is 8 cm, and since the rectangles are equal, the second side will be equal to half of the larger one.

Let’s calculate its length:

8/2 = 4 cm.

Let’s calculate what the perimeter of the rectangles is:

P = 2 * (8 + 4) = 2 * 12 = 24 cm.

Answer: the correct option is number 4, the perimeter of the rectangles is 24 cm.
