Answer:
let the breadth =b m
length = l =(2b+1)m
area =528m²
l*b= 528
(2b+1)b-528=0
2b²+b-528=0
2b²+33b-32b-528=0
b(2b+33)- 16(2b+33)=0
(2b+33)(b-16)=0
2b+33=0 or b-16=0
b should not be zero
therefore
b-16=0
b=16
breadth = 16m
length =l= 2b+1=2*16+1=32+1=33m

Answer:
- Let the Breadth be b
- Then, length will be 2b + 1
- It is given that Area of reactangular plot is 528 m².
According to question now :
Area = Length × Breadth
528 = (b) (2b + 1)
528 = 2b² + b
2b² + b - 528 = 0
Now, by using splitting term we get,
2b² - 32b + 33b - 528 = 0
2b (b - 16) + 33 (b - 16) = 0
(2b + 33) (b - 16) = 0
If x - 16 = 0, then x = 16
If 2b + 33 = 0, then b = -33/2
Therefore, Breadth = 16 meter.
So,
Length = 2b + 1 = 2(16) + 1 = 32 + 1 = 33 m
Hence,
Length of the reactangular plot = 33 m
Breadth of the reactangular plot = 16 m
