Hii


Find out the area of the rectangle by multiplying the sides ( 2n-1 ) and ( 2m-1 ) . try to convert calculated area into a complete square and as well as keep a check that square root of area is greater than or smaller than any of the sides.

Because the answer will change qaccording to that.



Thanks
