Está correcta en el siguiente problema:

El perímetro de un rectángulo es tres veces su largo. Si el largo mide 12 centímetros, ¿cuántos centímetros mide el ancho?

Answer :

Final answer:

The width of the rectangle is 6 centimeters.


Explanation:

The question is asking us to find the width of a rectangle given its length and the relationship between the perimeter and the length. Let's solve the problem step by step.



  1. We are given that the perimeter of the rectangle is three times its length. So, if the length is 12 centimeters, the perimeter would be 3 * 12 = 36 centimeters.

  2. The formula for the perimeter of a rectangle is P = 2L + 2W, where P is the perimeter, L is the length, and W is the width. Since we know that the perimeter is 36 centimeters and the length is 12 centimeters, we can substitute these values into the formula:


36 = 2 * 12 + 2W



  1. Simplifying the equation, we have:


36 = 24 + 2W



  1. Subtracting 24 from both sides:


12 = 2W



  1. Dividing both sides by 2:


6 = W


Therefore, the width of the rectangle is 6 centimeters.
