Answer :
Final answer:
The length of the fence of the rectangular dog lot, where the length is double the width and the total length of the fence is 120 feet, is 40 feet.
Explanation:
This question can be solved by using the formula for the perimeter of a rectangular shape, which is 2*(length + width). For this problem, we are given that the perimeter is 120 feet, and the length of the rectangle is double the width. Let's denote the width as 'w'. Therefore, the length is '2w'.
We set up the equation as follows: 2*(2w + w) = 120. Simplifying this, we get 6w = 120. Then, solving for 'w', we divide both sides by 6, and find that 'w' = 20 feet. Therefore, the length, being double the width, is 40 feet long.
