i got it right, hope this helps :D
Step-by-step explanation: Since the width and length are consecutive odd integers, call the width <em>x</em> and the length <em>x + 2</em>.
Now, it would be helpful to draw a picture of your rectangle
and label its parts to help you set up the equation.
Since the perimeter of the rectangle is 120 meters,
<em>x + x + (x + 2) + (x + 2) = 120</em>.
Simplifying from here we get 4x + 4 = 120.
Now subtract 4 from both sides to get 4x = 116.
Now divide both sides by 4 to get x = 29.
So the width of our rectangle is 29 meters
and the length, <em>x + 2</em>, is 31 meters,
