    Level of a playing field was raised by putting a 10 cm thick layer of soil at the rate of Rs. 15/m3. If the length of the field is 20m more than its width, find length of the field if Rs. 714 were spent in completing the task.
    Solutions
    Let the width of the field = x meters

    Length = (x+20) m

    Volume of layer of soil = (x)(x+20)(0.1)

    Cost of the work at Rs.15/m3 = (x)(x+20)(0.1)(15) = 714

    Solving for x gives, x = 14 m = width     

    Length = 14 + 20 = 34 m
