If i add 3 feet +6 inches + 8 feet+ 2 inches +4 inches + 2 feet + 5 inches whats the answer

Take all the foot measurements and add them up, and you get 13. Then take all the inches measurements and add them up to get another foot and 5 inches. So your final answer would be 14ft/5in.

First add up all of your inches (6+2+4+5) this equals 17 inches.
Then, convert this into feet. There are 12 inches in every foot, so 17 inches equals 1 foot and 5 inches.
After this, simply add up the feet (3+8+2). This equals 13 feet.
Finally, add 13 feet and 1 foot. This equals 14 feet.
Take your remaining inches (5) and add that after.

Your final answer is: 14 feet and 5 inches, or 14ft and 5in.

Hope this helps!
