The perimeter of the rectangle is 48cm, one of its sides is 2 times larger than the other, find the lengths of the sides of the rectangle.

Let’s solve this problem using the equation.
Let the first side of the rectangle be x centimeters, then the second side of the rectangle is 2 * x centimeters. We know that the perimeter of the rectangle is 48 centimeters. Let’s make the equation:
2 * (x + 2 * x) = 48
x + 2 * x = 48: 2;
x + 2 * x = 24;
x * (1 + 2) = 24;
x * 3 = 24;
x = 24: 3;
x = 8 centimeters – the length of the first side of the rectangle;
2 * 8 = 16 centimeters – the length of the second side of the rectangle.
Answer: 8 centimeters: 16 centimeters.
