Find the lengths of the sides of the triangle if one of them is 2.4 times less than the second and 2 times more than the third, and the perimeter of the triangle is 27.3 cm.

This problem will be solved by drawing up an equation;

Let x cm be the length of the first side of this triangle;

Then 2.4 * x cm is the value of the length of the second side of this triangle;

1/2 * x cm is the length of the third side of this triangle;

We also know the value of the perimeter of this triangle 27.3 cm, we draw up an equation of the following form:

x + 2.4 * x + 1/2 * x = 27.3;

3.9 * x = 27.3;

x = 27.3: 3.9;

x = 7.

7 cm is the length of the first side of this triangle;

7 * 2.4 = 16.8 cm is the length of the second side of this triangle;

1/2 * 7 = 3.5 cm is the length of the third side of this triangle.

Answer: 7 cm is the length of the first side of this triangle; 16.8 cm is the length of the second side of this triangle; 3.5 cm is the length of the third side of this triangle.
