The perimeter of the rectangle is 12 cm and the width is 22 cm less than the length. Find its length.

The perimeter of the rectangle is specified by the problem statement. Let’s find its length. Let the length be x cm, then the width of the rectangle will be (x – 22) cm.Let’s make an equation, knowing the formula for the perimeter of the rectangle:

P = 2 * (a + b), where a is the length of the rectangle, b is the width of the rectangle, P is the perimeter of the rectangle.

(x + x – 22) * 2 = 12;

2x – 22 = 12: 2;

2x – 22 = 6;

2x = 6 + 22;

2x = 28;

x = 28: 2;

x = 14 (cm) – the length of the rectangle.

Answer: 14 centimeters is the length of the rectangle.
