| Given:

One side of the rectangle is 2 times larger than the other.

The perimeter of the figure is 30 centimeters.

Let the second side of the quadrangle be x centimeters.

Then the length of the first side will be 2 centimeters.

Let’s make the equation:

x + x + 2x + 2x = 30;

6x = 30;

x = 30: 6;

x = 5.

One of the sides is 5 centimeters long.

Find the length of the second side:

5 * 2 = 10 centimeters.

Answer: The smaller side of the rectangle is 5 centimeters long.
