oh ur back...lol

anonymous · Answer

length/width =7/5
l = 7/5w
P = 2(l+w)
96 = 2(l +7/5 l)

ty!

Well, here you get two equations:$$\frac{ length(x) }{ width(y) }=\frac{ 7 }{ 5 }$$and$$2x+2y=96$$

30 ft by 18 ft
       28 ft by 20 ft
       24 ft by 24 ft
       22 ft by 26 ft

@sangya21  so which one of those is it?

anonymous · Answer

length/width =7/5
l = 7/5w
P = 2(l+w)
96 = 2(w+7/5 w) 
96/2 = (5w +7w)/5
48*5 = 12w 
240 = 12 w
w = 20 
l = 7/ 5* w
l = 7/5*20 
l = 7*4 = 28
