Given the area of a rectangular plot is 528m^2.

Let the breadth of the plot be 'b'.

Then, the length of the plot will be: = 2b +1.

Therefore the area will be:

=b(2b+1)\ m^2 which is equal to the given plot area 528m^2.

\Rightarrow 2b^2+b = 528

\Rightarrow 2b^2+b - 528 = 0

Hence, the length and breadth of the plot will satisfy the equation 2b^2+b - 528 = 0
