Scalene trian<span>gle

For area A, the width will be √(3A/4), so for the three rugs, the widths are 6 ft, 9 ft, 12 ft. Corresponding lengths are 4/3 times that, so are 8 ft, 12 ft, 16 ft.
The rug dimensions are
.. 6 ft x 8 ft
.. 9 ft x 12 ft
.. 12 ft x 16 ft
Pick the one(s) that are on your list.
4x+6<-6
minus6 both sides
4x<-12
divide 4 both sides
x<-3
x is any number less than -3
try -100
4(-100)+6<-6
-400+6<-6
-394<-6
true
x<-3
Assuming the ratio of 4:5 represents the ratio of width:length then we can set up a simple proportion to find the length...

L = 5(28)÷4
L = 35
Now we can find the perimeter and area of the rectangle:
A = LW
A = 28(35) = 980
P = 2L + 2W
P = 2(35) + 2(28) = 126
Answer:
x= 9
