The length of the rectangle is 9 cm and the width is 3 times less than the length. Find its perimeter.

To solve the problem, first find the value of the width of the rectangle.

Since the condition indicates that the width is 3 times less than the length, for this we divide 9 cm by 3.

We get:

9/3 = 3 cm.

Find the perimeter of the shape, which is the sum of all the sides of the rectangle.

In this case, we get:

2 * (9 + 3) = 2 * 12 = 24 cm.

Verification of the solution.

9 + 3 + 9 + 3 = 12 + 12 = 24 cm.

The area of the figure will be equal to:

9 * 3 = 27 cm2

Answer: The perimeter of the rectangle is 24 cm.
