    Answer:

    450 units squared

    Step-by-step explanation:

    2(length)+2(width)=Perimeter

    W=x     Length=15+3w   Perimeter=110

    2(15+3w)+2w=110

    30+6w+2w=110  

    8w=80

    w=10

    So:  Length is 45 and Width is 10

    Area is l*w

    Area=45*10

    Area is 450 units squared
