Sabrina has a rug with a perimeter of 18 feet. she decides to place a border around the rug so that the new length of the rug is 8 feet and the width is 4 feet. the border is the same width all the way around. the equation which represents x, the width of the border is 2(8-2x)+ 2(4-2x)=18. what is the width of the border?

a. 3/4

b. 1 1/2

c. 1 ft

d. 3 ft

The answer is: a.

Since we are given the equation which represents the width of the border (x) we only need to isolate the variable (x), so:

So, the width of the border is:

Have a nice day!

ratio is 2 : 9

the answer is three

13.5 : 3
