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
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
