Question

solve The area of a rectangular plotis 528 m. The length of the plot in metres) is one more than twice its breadth We need to find the length and breadth of the plot by using the quadratic formula​

Answer 1

Step-by-step explanation:

hey mate

here

let the length be x

and breadth be y

then

area = length *breadth

= xy

thus

xy= 528

now

given

length is two more than twice the breadth

it means

x = 2y +2

now

putting x =. 2y+1. in the first condition, we get

(2y+2)* y = 528

=> 2y^2+2y= 528

=> 2y^2+2y-528= 0

=> 2y^2+ 24y-22y-528= 0

=> 2y(y+12)-22(y+12)=0

=> (y+12)(2y -22)

so

y= -12. ( or) 11

then length = 22+2= 24m

and breadth = 22m

hope it helps

there was one mistake in the question that breadth should be two more than twice the length

so don't be confused

hope it helps ✌
