area of plot =528m²
let the breadth be x
then the length will be 2x+1
according to the question
area= l×b
= 2x+1 (x)=528
= 2x²+x=528
=2x²+x-528=0
=2x²+33x-32x+528=0
=2x²-32x+33x+528=0
2x(x-16)-33(x-16)=0
2x-33 is impossible
therefore x=16
hence
length =2×16+1
=32+1
=33
and breadth = 16

Let breath =x, length =2x+1
Area of rectangle =528
L*b=528
(2x+1)(x)=528
2Xsq +X=528
2Xsq+X-528=0
Hope it will help you
