Calculate the area of a rectangle, the perimeter of which is 32 cm, and the length of one side is one

Calculate the area of a rectangle, the perimeter of which is 32 cm, and the length of one side is one third of the length of the other side.

Let’s solve this problem through the equation.
1) Let the length of one side of the rectangle be x centimeters, then the length of the other side of the rectangle is 3 * x centimeters. We know that the perimeter of this rectangle is 32 centimeters. Let’s make the equation:
x + 3 * x = 32;
x * (1 + 3) = 32;
x * 4 = 32;
x = 32: 4;
x = 8 centimeters – the length of one of the sides of the rectangle;
2) 8 * 3 = 24 centimeters – the length of the second side of the rectangle;
3) 8 * 24 = 192 square centimeters – the area of a rectangle.
Answer: 192 centimeters square.
