Answer: the perimeter of the rectangle is 108 cm.
We can determine the width of the rectangle if it is known that it is 2 times less than the length equal to 36 cm:
36/2 = 18 cm.
It is customary to call the perimeter of any polygon the sum of the lengths of all its sides.
In addition, the opposite sides of the rectangle are equal to each other, therefore, to calculate the perimeter of the rectangle, it will be enough to know the values of its length and width:
36 + 36 + 18 + 18 = 108 cm.
