# One side of the rectangle is 2 times longer than the other, the total length

**One side of the rectangle is 2 times longer than the other, the total length of these two sides is 12 centimeters, find the length of each side of this rectangle.**

Let’s solve this problem using the equation.

Let the length of the first side of the rectangle be x centimeters, then the length of the second side of the rectangle is 2 * x centimeters. We know that the total length of these two sides of the rectangle is 12 centimeters. Let’s make the equation:

x + 2 * x = 12;

x * (1 + 2) = 12;

x * 3 = 12 (in order to find an unknown factor, you need to divide the product by a known factor);

x = 12: 3;

x = 4 centimeters – the length of the first side of the rectangle;

4 * 2 = 8 centimeters – the length of the second side of the rectangle.

Answer: 4 centimeters; 4 centimeters; 8 centimeters; 8 centimeters.
