A 6 cm square was cut into two rectangles. The perimeter of one of these rectangles is 16 cm. What is the perimeter of the other?

The side of the square is 6 centimeters.
The perimeter of one rectangle is 16 centimeters.
The length of the rectangle is equal to the side of the square.
Let’s calculate the width of the rectangle:
(16 – 6 – 6): 2 = 4: 2 = 2 centimeters.
Let’s find the width of another rectangle, since the two widths of different rectangles make up the length of the square:
6 – 2 = 4 centimeters.
Let’s calculate the perimeter of the second rectangle:
4 + 4 + 6 + 6 = 20 centimeters.
Answer: 20 centimeters.
