Detailed Solution

Given that the area of a rectangular plot is 528 m².
Also, given that the length of the plot (in meters) is one more than twice its breadth.
Let the breadth of the rectangular plot be x.
So, length = 1+2x.
Area of the rectangular plot = length × breadth.
528= 1+2x x    528=x+2 x 2  
Take the term on left side to the right side of the equation, we get
2 x 2 +x528=0   The given situation is represented by the quadratic equation 2 x 2 +x528=0  .
Therefore,  the correct option is 1.
