Question 521944
Area = L*W															
Area =	660	sq. 	ft												
															
															
Area =	600	sq. yd													
Width 	=		x	yd											
Length 	=(3x-5	)
Area =x	*(3x-5	)
600	=3x^2-5x			
3x^2-5x	-600=0	
Find the roots of the equation by quadratic formula						
						
a=	3	,b=	-5	,c=	-600	
						
b^2-4ac=	25	+	7200			
b^2-4ac=	7225					
{{{x=(-b+-sqrt(b^2-4ac))/(2a)}}}						
{{{x1=(-b+sqrt(b^2-4ac))/(2a)}}}						
{{{x1=(-12+21)/(12)}}}						
x1=(	5	+	85	)/	6	
x1=	15					
x2=(	5	-85	) /	6		
x2= 	-13.33		Ignore negative value

width = 15 yd
length = 40 yd

check
Area = 15*40 = 600
