    Hi Komal

    Cost of Ploughing the square field = Rate of ploughing x Area of Square

     

    Now, given that

    Rate of ploughing per 10 square meter = Rs 2

    Rate of ploughing per 1 square meter = Rs 2/10

     

    And,

    Area of Square = (Side)2

     

    Now, putting values in equation

    Cost of Ploughing the square field = Rate of ploughing x Area of Square

    2450 = 2/10 x (Side)2

    2450 x 10/2 = (Side)2

     

    (Side)2 = 2450 x 10/2

    (Side)2 = 12250

    Side = root(12250)

    Side = 110.679 m

     

    Thus, length of square  = 110.679 m

    Do you want us to show you how to calculate square root?
