First, based on the conditions of the problem, we determine the width of the rectangle, for this we translate decimeters into centimeters (1 dm = 10 cm): 3 dm – 8 cm = 30 cm – 8 cm = 22 cm.
Since the perimeter of the rectangle is equal to the sum of all its sides, we find it:
30 cm + 30 cm + 22 cm + 22 cm = 104 cm.
Answer: the perimeter of the rectangle is 104 cm.
