Calculate the area and perimeter of a rectangle that is 18 cm long and 6 times less wide.

1) Calculate the width of a given triangle if it is known that its length is 18 cm, and its width is 6 times less:
18: 6 = 3 cm.
2) Find the area of this rectangle, knowing that it is equal to the product of its length and width:
18 * 3 = 54 cm ^ 2.
3) Find out what the perimeter of the rectangle is if it is defined as the sum of the lengths of all sides of the rectangle:
18 + 3 + 18 + 3 = 42 cm.
Answer: the area of the rectangle is 54 cm ^ 2, the perimeter is 42 cm.
