A rectangular room is 3 times as long as it is wide

A rectangular room is 3 times as long as it is wide and its perimeter is 64 meters. Find the dimensions of the room.

Define the Width:

We start by defining the width of the room as w meters.
Why? Because we need a starting point, and the width is a basic dimension of the rectangle.
Define the Length:

The question states that the room is "3 times as long as it is wide."
Therefore, we define the length as 3w meters.
Why? Because the length is 3 times the width, as stated in the question.
Understand Perimeter:

The perimeter of a rectangle is calculated as P = 2 * (length + width).
Why? Because that's the formula for the perimeter of a rectangle.
Plug in Given Perimeter:

We know the perimeter is 64 meters, so we set P to 64.
This gives us the equation 64 = 2 * (3w + w).
Why? Because we're using the given perimeter to find the dimensions.
Combine Like Terms:

Inside the parentheses, combine 3w and w to get 4w.
Now the equation is 64 = 2 * 4w.
Why? Because we're simplifying the equation to make it easier to solve.
Distribute the 2:

Multiply 2 by 4w to get 8w.
The equation becomes 64 = 8w.
Why? Because we're simplifying the equation further.
Isolate w:

To find w, divide both sides of the equation by 8.
w = 8 meters.
Why? Because we're solving for w, which represents the width.
Find the Length:

Now that we know w, we can find the length.
The length is 3 * 8, which is 24 meters.
Why? Because the length is 3 times the width.
