The length of a rectangular room is 2 feet longer than twice the width. if the room's perimeter is 196 feet, what are the room's dimensions?

Using a system of equations, it is found that for the room's dimensions:

The perimeter of a rectangle of length l and width w is given by:

The length of a rectangular room is 2 feet longer than twice the width, hence:

The room's perimeter is 196 feet, hence:

From the second equation:

Then:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
