The length of a rectangular hall is 5m more than its breadth . if the area of the hall is 594 square metre , find its perimeter.

Let the lenght and breadth be -- x

$<font color=yellow>$

Area = L×B

594 = (x+5)*(x)

594=x²+5x

Perimeter of rectangle = 2(l+b)

=2(x²+5x)

2x²+10x

=> x²+5x=2x²+10x

=>x²-2x²=5x-10x

=>x²=5x

_______________________________

---------------------------------

=> area = 594=x+5×x

$=> 594= x^{2}+5x$

=> $6x^{2}=594$

=> $x^{2}=594/6$

=> $x=\sqrt{99}$

=> $x=9.94$

_________________________________

perimeter of rectangle=2(l+b)

=>2(9.94)

=>19.88
