Answer:
———————
6.75 feet |
———————
Step-by-step explanation:
Let the width be x. If the width is x, the the length has to be 3x because in the question it says that the length is 3 times the width.
Since this is a rectangle, the opposite side has the same measure, like in the attachment below.
To find the perimeter, you would add up all the sides.
3x+3x+x+x
=6x+2x
=8x
It is also given in the question that he uses 18 feet. Which means that the perimeter is 18 feet. But you figured out that 8x is ALSO the perimeter. This means that you can say: 8x=18.
Solve for x, 18/8=9/4=2.25.
You want the length, which is 3x. So 3(2.25) is your answer.
3(2.25) = 6.75
I don't see any answer choices, so I'm just going to attach an image of the equations graphed on Desmos.
Desmos is a free, online graphing calculator that works really well for problems like this. If you want to get a better view of the graphs and to be able to "interact" with them, just go to the desmos website and put in your equation(s). The picture that I've attached might not be very helpful because it doesn't show the full extent of the graph, so you might want to check it out and do it yourself.
Hope this helps!
