    It is 3 feet wide

    Step-by-step explanation:

    perimeter is the boundary of a closed geometric figure aka total of all sides

    rectangle guarantees opposite sides are equal

    multiply both lengths 7*2=14

    Subtract the two lengths from the perimeter 20-14=6

    Divide the two widths by 2 to get one 6/2=3
