    Answer:(3) 33 m
    Explanation:-
    The breadth of the rectangle = 25 m
    Cost of a grass bed on this field  = Rs.12375
    Cost of per sq. m. = Rs.15

    Therefore, the area of the field = 12375/15
    = 825 m2
    Let be the length is X mitre.
    Area of rectangle = Length x breadth
    X x 25 = 825
    X = 825/25
    X = 33 mitres

    Hence, the length is 33 mitres of a rectangle field.
