    I am stuck here as the variable y is unknown and I want to express y in terms of x, but cannot figure out how to do so.
    Thanks for any help!

    You're told that the perimeter is fixed, which means that P is some constant. You can represent y in terms of P and x so that you then have the area A in terms of just one variable x.
