Hey.
Given area of the plot = 528 m^2
Let breadth of the plot be x m
Then length = 2x + 1 m
As, area of rectangle = length × breadth
so, 528 = (2x+1)x
or, 528 = 2x^2 + x
or, 2x^2 + x - 528 = 0
So, breadth is 16 m
and length = 2×16 + 1 = 33 m
Thanks.

t is an linear equation. So *=multiply
Let the breadth be:x
Therefore, the length: 2x+1
According to the condition -
Area of rectangular plot=l*b
528 =x[2x+1]
528 =2x2+1x
0 =2x2+1x-528
0 =2x2+33x-32x-528
0 =x[2x+33]-16[2x+33]
0 = [2x+33] [x-16]
2x+33=0 OR x-16=0
2x =-33
x=16 x =-16.5
Area cannot be negative
Therefore x=16 is the solution
length=1+2x breadth=x
=33m =16
