The width of the rectangle is 3 times less than the length. The perimeter of this rectangle is 48 cm.

The width of the rectangle is 3 times less than the length. The perimeter of this rectangle is 48 cm. Find the area of the rectangle.

The solution of the problem:
Let’s solve the problem using the equation.
1. The width of the rectangle is x centimeters.
2. Determine what is the length of the rectangle.
x * 3 = 3x centimeters.
3. Let’s compose and solve the equation.
x + x + 3x + 3x = 48.
8x = 48.
x = 48/8.
x = 6.
4. The width of the rectangle is x = 6 centimeters.
5. Determine the length of the rectangle.
3x = 3 * 6 = 18 centimeters.
Let’s answer the question of the problem.
6. Find what the area of the rectangle is.
6 * 18 = 108 square centimeters.
Answer: The area of a rectangle is one hundred and eight square centimeters.
