The side of the square is 10 cm. A square piece was cut from the square, the side of which is 5 cm. What is the perimeter of the remaining part?
The perimeter of a square can be considered the sum of all its sides.
In the initial case, the perimeter of the square was:
10 + 10 + 10 + 10 = 40 cm.
Since a square piece with 5 cm sides was cut, it means that 2 sides of 10 cm and 4 sides of 5 cm remain from the initial square.
In this case, the perimeter of this figure was:
10 + 10 + 5 + 5 + 5 + 5 = 40 cm.
Answer: The perimeter has remained unchanged and is 40 cm.
