The length of the rectangle is 12 cm, and the width is 2 times less than the length. Accordingly, the width will be 12: 2 = 6 cm.
The perimeter of the rectangle is the sum of the lengths of all sides.
We get:
12 + 12 + 6 + 6 = 36 (cm)
or the second way:
(12 + 6) * 2 = 36 (cm)
Answer: the perimeter of the rectangle is 36 cm.
