    Step-by-step explanation:

    width of rectangle(w)=x let

    length (l)=4x

    perimeter of rectangle=70

    2(l+w)=70

    2(4x+x)=70

    8x+2x=70

    10x=70

    x=70/10

    x=7

    again,

    • length =4x=4×7=28cm
    • width=x=7

    area of rectangle =l×w

    • 7×28
    • 196cm²

    hope it helps.
