The length y of a rectangle is four less than three times the width x. The perimeter of the rectangle is 16 cm.

There is no requirement in the question. I'll calculate the area of the rectangle to help you with this question.

Step-by-step explanation:

System of Equations

Let's call y to the length of a rectangle, x to its width. There are two conditions that will help us to solve for x and y.

Divide by 2:

To solve the system, we'll substitute the y in the first equation into the second:

Joining like terms:

Solving:

Find the value of y:

Thus, the length of the rectangle is 5 cm and its width is 3 cm. The area is calculated as:
