First, we can calculate the width of the rectangle, which, as is known from the problem statement, is 3 times smaller than the length of this rectangle:
9: 3 = 3 dm.
The perimeter of a rectangle is calculated as the sum of the lengths of all its sides. A rectangle has equal sides in pairs.
Thus, we calculate the perimeter of this rectangle:
P = 9 dm + 9 dm + 3 dm + 3 dm = 24 dm.
Answer: The perimeter of the rectangle is 24 dm.
