1. S is the area of the rectangle. The perimeter of the rectangle (P) = 24 centimeters. AD is 3 times AB.
2. By the condition of the problem AD is 3 times more than AB. Therefore, AD = 3AB.
3. P = 2 (AB + AD) = 24 centimeters.
AB + blood pressure = 12 centimeters.
We substitute 3AB instead of AD in this expression:
AB + 3AB = 12 centimeters.
4AB = 12 centimeters.
AB = 3 centimeters.
BP = 3 x 3 = 9 centimeters.
4. S = AB x AD = 3 x 9 = 27 centimeters².
Answer: S is equal to 27 centimeters².
