Okay. This is another perimeter problem.
To solve this, let's express length and width as variable equations:
Length=2x+10
Width=x
That means two times the length plus two times the width should be the perimeter, which in this case is 80.
In equation format, this would mean:
Simplified: (factor it out)
Simplified: (combine like terms)
Simplified: (isolate variables)
Simplified: (simplify)
That means:
and , which simplifies to .
I hope that helps. :)
