    Answer:

    11) Length = 75 cm

    Breadth = 25 cm

    Explanation:

    Let assume that length is x and breadth is y. then,

    Given,

    Perimeter of rectangle = 200 cm

    x = 3 (y)

    x = 3y …(eq 1)

    We know that,

    Perimeter of rectangle = 2 ( x + y)

    200 cm = 2 ( x + y) …(given)

    200 cm = 2 (3y + y) …(from eq 1)

    100 cm = 4y

    100/4 = y

    y = 25 cm

    Therefore we get y putting in equation one.

    x = 3y

    x = 3 (25) cm

    x = 75 cm

    Hence, Length, x = 75 cm and Breadth, y = 25 cm.

    Thankyou

    I hope it is helpful to you.

    Answer:

    Ok

    Step-by-step explanation:

    Length = 3x

    Breadth = x

    8x= 200

    X= 200/8

    X =25

    Breadth = 25cm

    Length = 75cm
