The length of the rectangle is 9cm, and the width is 3 times less. find the perimeter and area.

The perimeter is equal to the sum of the lengths of all sides of the rectangle, and the area is equal to the product of the length by the width.

Let’s find the width of the rectangle:

9: 3 = 3 cm;

Knowing the length and width, we can find the perimeter and area:

P = 3 + 3 + 9 + 9 = 24 cm;

S = 3 * 9 = 27 cm2.

Answer: 24 cm, 27 cm2.
