Answer:
Length: 12 meters
Step-by-step explanation:
Step 1:
Let us start with the formula of the perimeter of a rectangle, , where <em>l</em> represents the length of the rectangle, and <em>w</em> represents the width of the rectangle.
We can set width as variable <em>x</em>. We are also given that the length is three times the width, hence it can be represented as <em>3x</em>.
Step 2:
We can now write our equation and solve for <em>x</em> :
We set <em>x</em> as width, so the width is 4 meters. However, in this problem we are looking for the length. The length is three times the width, so it would be meters.
