| It is clear from the conditions of the problem that the rectangle was mentally divided into five equal parts. Since the perimeter is measured in centimeters, it becomes clear that 1/5 or 30 cm is conventionally 1/5 of the entire perimeter. If the entire perimeter is equal to one or 5/5, then, in order to find the entire perimeter, you need to multiply 30 by 5 such parts.
