All sides of the triangle have a length of 12 cm. Each side has been reduced by 2 cm.

All sides of the triangle have a length of 12 cm. Each side has been reduced by 2 cm. Find the perimeter of the resulting triangle.

To solve this problem, we introduce the conditional variable “X”, through which we denote the perimeter of the new triangle.

Let’s take into account the fact that the side of the new triangle will be equal to 12 – 2 = 10 centimeters.

Then, based on the data of the problem, we will compose the following equation: X = 10 x 3.

Solving this equation, we get X equal to 30 centimeters.

Answer: The perimeter of the new triangle is 30 centimeters.
