1.	ng Situaions Ih the form of quadratic equationsG) The area of a rectangular plot is 528 m2. The length of528 m2. The length of the plot (in metres) is onemore than twice its breadth. We need to find the length and breadth of the plot.
Answer» Let the breadth =b mlength = l =(2b+1)marea =528m² lb= 528(2b+1)b-528=0 2b²+b-528=02b²+33b-32b-528=0b(2b+33)- 16(2b+33)=0(2b+33)(b-16)=02b+33=0 or b-16=0 b should not be zerothereforeb-16=0b=16 breadth = 16mlength =l= 2b+1=216+1=32+1=33m

Answer»

Let the breadth =b mlength = l =(2b+1)marea =528m²

l*b= 528(2b+1)b-528=0

2b²+b-528=02b²+33b-32b-528=0b(2b+33)- 16(2b+33)=0(2b+33)(b-16)=02b+33=0 or b-16=0

b should not be zerothereforeb-16=0b=16

breadth = 16mlength =l= 2b+1=2*16+1=32+1=33m
