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
