    75

    Step-by-step explanation:

    x=breadth

    3x=length

    perimeter=2 (x+3x) = 8x

    40=8x

    x=5

    length=15

    breadth=5

    area=15*5=75

    75 yd^2.

    Step-by-step explanation:

    If the width = x yards, the length will be 3x yards.

    The perimeter = 2 * length + 2 * width

    = 2 * 3x + 2*x = 40

    6x + 2x = 40

    8x = 40

    x = 5

    So the width is 5 and the length is 15 yards.

    The area = 5 * 15 = 75 yd^2.
