The width of the rectangle is 9 cm and the length is 3 times larger. Find the perimeter and area of the rectangle.

1) Find the length of the rectangle:

9 * 3 = 27 cm.

2) The perimeter of a rectangle is equal to the sum of its length and width, multiplied by 2:

P = (a + b) * 2, which means:

(27 + 9) * 2 = 72 cm.

3) The area of a rectangle is equal to the product of its sides:

S = a * b, therefore:

27 * 9 = 243 cm².

Answer: the perimeter of the rectangle is 72 cm, the area of the rectangle is 243 cm².
