PLEASE HELP

  • math algebra - ,

    length is twice the width
    L = 2W

    area is length times width.
    72 = (2w(w)
    72 = 2w^2
    divide both sides by 2 to get 36 and then take the square root of 36 to find "w". double that value to find the length. Check by multiplying l times w to see if you get 72.
