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» 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 ✌ mark me as a bainlist and follow me too |
