Answer:
i. 6 feet by 3 feet
ii. 7 feet by 2 feet
iii. 8 feet by 1 feet
Step-by-step explanation:
From the given question, we have;
length of the rectangular fence, l = 6 feet
perimeter of the rectangular fence = 18 feet
Let the width of the rectangular fence be represented by w.
So that,
Perimeter of a rectangle= 2(length + width)
18 = 2(6 + w)
18 = 12 + 2w
18 - 12 = 2w
6 = 2w
w = 
w = 3
The width of the rectangular fence would be 3 feet when the length is 6 feet.
Thus, the possible dimensions of the rectangular fence are:
i. 6 feet by 3 feet
ii. 7 feet by 2 feet
iii. 8 feet by 1 feet
