    Let length and breadth of rectangle be 2x and 3x respectively.

    Area of rectangle = 150cm²

    Length × breadth = 150

    2x × 3x = 150

    6x² = 150

    = 150/6

    = 25

    x = 25

    x = 5

    ______________

    ______________

    Length = 2x = 2×5 = 10cm

    Breadth = 3x = 3×5 = 15cm

    Answer:

    Let the length and breadth be 3x and 2x

    A/q. 2x(3x)=150

    6x^2=150

    x=√25=5cm

    length=3×5=15 cm
